FASTGRID – Cost effective FCL using advanced superconducting tapes for future HVDC grids

Project leader:	doc. Ing. Gömöry Fedor, DrSc.
Annotation:	Sustainability of energy systems goes through high penetration of renewable energy with huge volumes of electricity to transmit over long distances. The most advanced solution is the HVDC Supergrid. But fault currents remain an issue even if DC circuit breakers have emerged. These are not satisfying, whereas Superconducting Fault Current Limiters (SCFCLs) using REBCO tapes bring an attractive solution. SCFCLs have already proved their outstanding performances in MVAC systems, with a few commercial devices in service. However, present REBCO conductors cannot be readily used at very high voltages: the electrical field under current limitation is too low and leads to too long tapes and high cost. FASTGRID aims to improve and modify the REBCO conductor, in particular its shunt, in order to significantly enhance (2 to 3 times) the electric field and so the economical SCFCL attractiveness. A commercial tape will be upgraded to reach a higher critical current and enhanced homogeneity as compared to today’s standards. For safer and better operation, the tape’s normal zone propagation velocity will be increased by at least a factor of 10 using the patented current flow diverter concept. The shunt surface will also be functionalized to boost the thermal exchanges with coolant. This advanced conductor will be used in a smart DC SCFCL module (1 kA, 50 kV). This one will include new functionalities and will be designed as sub-element of a real VDC device. In parallel to this main line of work, developments will be carried out on a promising breakthrough path: ultra high electric field tapes based on sapphire substrates. FASTGRID will bring this to the next levels of technology readiness. In conclusion, FASTGRID project aims at improving significantly existing REBCO conductor architecture to make SCFCLs economically attractive for HVDC Supergrids. However, availability of such an advanced conductor will have an impact on virtually all other applications of HTS tapes.

TRANSCOE – Development of new designed transparent conductive electrodes for organic electronics
Vývoj nových vodivých priehladných elektród pre organickú elektroniku
Program:	Bilateral – other
Project leader:	Ing. Fröhlich Karol, DrSc.
Annotation:	Subject of the proposed project is preparation of new transparent conductive electrodes with high transparency and low sheet resistance for organic photovoltaic\’s (OPVs) and organic light emitting diodes (OLEDs). The project will focus on five issues; i) electrode design ii) synthesis of conductive electrodes; iii) fabrication, characterization and optimization of transparent electrodes; iv) fabrication and characterization of OPVs and OLEDs to test the performance of the prepared transparent conductive electrodes; v) encapsulation. We will prepare OPVs and OLEDs with incorporated novel electrode design and test the performances of the devices when the electrode materials will be deposited on glass and/or flexible substrate. Transparent conductive electrodes will be based either on organic Ag-nanowire network -organic multilayered structure or on atomic layer deposited Al-doped ZnO films. The electrodes will be characterized and optimized by measuring the sheet resistance and light transmission. The sheet resistance of the electrode should be adjusted to below 12 Ω and 50 Ω sq−1 for organic and Al-doped ZnO films transparent electrodes, respectively. Finally, OPVs and OLEDs will be encapsulated using atomic layer deposited thin films and their performance will be examined. Proposed project includes two different approaches of transparent conducting electrodes preparation for OPVs and PLEDs. Evaluation of performance of these two types of electrodes presents important and unique output of the project. As a result of the project A step to commercialization of new transparent conductive electrodes, OPVs and OLEDs will be achieved through international collaboration. Funding of the proposed project will create seed for setting up a new research on flexible electronics, Organic Field Effect Transistors (OFETs), Organic Thin Film Transistors (OTFTs), and nanotechnology applications in electronic and photonics for both partners.

Registration code:	2/0150/18
Program:	VEGA
Project leader:	Ing. Tóbik Jaroslav, PhD.
Annotation:	The subject of micro-magnetism studies are phenomena which are possible to describe on classicallevel of the theory. Micromagnetism describes processes in devices like bit-patterned media in harddisks,magnetic memories, magnetic radio-waves detectors, or bio and medical applications. Typicaldimensions of the devices active parts are order from micro-meter to few nanometers. Typical operationtemperature is room temperature. Usual model for these condition is classical physics. The mainproblem of the magnetic state stability simulation is the time-scale on which the magnetic statetypically persist. The magnetic state in memories is stable for years. There are several effectivealgorithms for finding lowest energy paths among metastable states. In order to search for stablemagnetic states effectively, we decided to implement matadynamics algoritm into micro-magneticsolvers.

Project leader:	Ing. Kuzmík Ján, DrSc.
Annotation:	Gallium Nitride (GaN) and related compounds commonly referred as III-N have significantly more flexible energy gap, higher breakdown electric field intensity, a large spontaneous polarization, high thermal and radiation resistance, but also the high mobility of electrons. Therefore there is an effort to develop III-N semiconductor devices, mainly HFETs, which have the potential to gradually replace Si, Si/SiGe, GaAs and InP devices in microwave and power applications, switches, switching amplifiers, logic circuits and mixed-signal electronics. Consequently, in this manner we aspire to develop HFETs with InN channel for ultra-fast information transfer, advanced GaN-based transistor switches for energy conversion, technology of GaN-based fast mixed-signal electronics, and GaN-based UV sensors for space applications.

Magnetické plášte z kompozitov supravodič/feromagnetikum
Registration code:	16-0418
Program:	SRDA
Project leader:	doc. Ing. Gömöry Fedor, DrSc.
Annotation:	Realization of a magnetic cloak allowing to hide objects from being observed by a magnetic detector enables the experimental study of several fundamental problems of electromagnetism as well as the searching for innovative solutions of practical problems of magnetic field shielding and shaping. Main aim of the project is the development of methods for design and realization of magnetic cloaks that would provide the possibility to investigate these topics. Basic property we will pursue is the magnetic invisibility when a detector placed outside the cloak will not notice the cloak itself nor a “magnetic cargo” it would contain. Theoretical predictions for reaching perfect invisibility assume unrealistic properties of the used materials and work with ideal and simple shapes without any limitation of dimensions. That is why an important part of the project will be the search and testing of new numerical modelling methods able to include these substantial aspects of real objects. With help of these novel methods we plan to demonstrate the 99% perfection in magnetic invisibility at frequencies from DC to 1000 Hz. Our research could help to reach the following goals: a) Creation of space for experiments in biology shielding the Earth magnetic field as well as that produced in urban environment. Room temperature cylindrical space with at least 50 mm diameter and 150 mm height should allow easy sample exchange and manipulation. b) Design and manufacturing of the cloak for magnetic fields in the 0.1 T range with the volume exceeding 1000 cm3 for the purpose of protecting a sensitive electronic circuitry or e.g. formation of working space for DC arc welding in vicinity of electrical machines generating the stray field at this level. c) Investigation of force exerted on the cloak by a non-uniform magnetic field, in particular the possibility of a magnetic propulsion with help of controlling the magnetic moment of the superconductor/ferromagnet composite.

Project leader:	Ing. Osvald Jozef, DrSc.
Annotation:	The project is oriented towards physical problems of III-V and III-N semiconductors. Many problems with these semiconductors are not solved yet or we have not their technological solution. Among these questions we may name in first the problems connected with the physics and chemistry of an interface between a semiconductor and a dielectric, solving of which is crucial for quality of this interface. The density of interface states of the prepared samples and structures depends directly on the solution of these problems and a possible presence of Fermi level pinning at the semiconductor surface, too. By III-V MISFET structures we want to study frequency dependence of capacitance curves. There are theories that in accumulation a dispersion of the capacitance is caused by a low density of states at the bottom of the conduction band and that the capacitance increase in inversion is connected with the states in the middle of the gap. We shall try to verify these theories or maybe modify them on the basis of the obtained results.

Annotation:	Surfaces of III-V semiconductors exhibit large densisties of surface states that limit the use of the semicondutorsin electronics. Native oxides on III-V surfaces do not match the qualiy of oxides on the surface of silicon. Thesurface states have been studied and manipulated by many researchers with the aim to eliminate their infuence.Our aim is to find out how technology is used to eliminate or passivate the states. We intend to useheterostrucutres whose surface will be manipulated to allow for the preparation of high quality MOSHFETs.Manipulation with surface states leads to new types of device. It will thus be possible to integrate various types oftransistor on a single wafer. To explore properties of individual layers of heterostructure by optical measurementwill necessite their release from original substrates and transfer to host substrates. Procedures of heterostructurerelease and transfer will be used in the integration of other semiconductor devices on planar and non-planarsubstrates.

Program:	SRDA
Project leader:	Dr. rer. nat. Hulman Martin
Annotation:	Two-dimensional (2D) materials have been one of the most extensively studied classes of materials due to their unusual physical properties. The best example is graphene – a single layer of carbon atoms arranged in a two dimensional (2D) honeycomb lattice. Many graphene´s extraordinary properties have been reported including excellent electronic and thermal conductivities and mechanical properties. Its discovery has also stimulated an extensive research on other 2D materials. It has been shown that it is not only possible to exfoliate stable, single-atom thick 2D materials, but that these materials can exhibit unique and fascinating physical properties. The 2D structure determines the electronic properties that may exhibit correlated electronic phenomena such as charge density waves and superconductivity. In this project, we focus on preparation of ultrathin (< 10 nm) films and monolayers of materials from the family of transition metal dichalcogenides (TMDs). The goal is to prepare those layers on a centimetre-large scale. For that, pulsed laser deposition and magnetron sputtering are the methods of our choice. As-prepared layers will then be thoroughly characterised in terms of their thickness, crystallinity, homogeneity, optical and electrical properties. As a next logical step, we will proceed in preparation of heterostructures and hybrids – systems where different TMDs materials and TMDs and graphene or graphene oxide are stacked on top of each other, respectively.

Composite superconductor MgB2 made by internal Mg diffusion
Kompozitný supravodič MgB2 na báze difúznej metódy
Registration code:	2/0129/16
Program:	VEGA
Project leader:	Ing. Kováč Pavol, DrSc.
Annotation:	The goal of this project is to prepare superconducting wire (filament) using new method of diffusion of magnesium (IMD) into the boron layer. The usability of this method is regarded by resulting very high density of superconducting part in the composite. One of the purpose is to optimize the IMD technique in that way, that dense MgB2 wire reach very high critical current density Jc comparing to older techniques (ex situ, in situ). We can expect improvement of important technical parameters like critical current density in low magnetic fields (< 3 Tesla) and critical temperature to be competitive also for low temperature superconductors (Nb3Sn, NbTi, Nb3Al …), having another advantage of more efficient cooling technique without the liquid helium.

Pinning in commercial coated conductors
Pinning v komerčných coated vodičoch
Registration code:	1633/03/01-b
Program:	SASPRO
Project leader:	Mgr. Seiler Eugen, PhD
Annotation:	The project will investigate pinning mechanisms in commercial ReBCO coated conductors coming from different industrial producers. Different manufacturing processes incorporate various kinds of pinning centers into functional superconducting layers of these conductors and as a consequence a very diverse mixture of pinning centers with dissimilar strength dependence on temperature and magnetic field can be found. Main focus will be on the temperature and magnetic field range interesting for applications in electric machinery (electric motors, generators, transformers, etc.) – temperatures 65 K to 77 K and fields 0 to 5 T. The aim is to identify which of the pinning mechanism is the most effective in the temperature and field domain of our interest and develop experimental techniques for its classification and description. Scaling of the critical current density and of the depinning activation energy with temperature and applied magnetic field will be experimentally characterized for all the commercial ReBCO coated conductors considered. At first the experiments in a broad range of available temperatures (4.2 K to 77 K) and applied magnetic fields (0 to 14 T) will be performed, focusing in the second stage on the domain perspective for the electric machinery applications. The experimental results will be compared with the predictions of available pinning models in order to determine and distinguish the different pinning mechanisms. Project combines experimental activity with application and development of theoretical models. Basic experimental techniques will be magnetization loop measurements and magnetic relaxation measurements in the Vibrating Sample Magnetometer, combined with transport measurements of current-voltage characteristics at various orientations of applied magnetic field.

Cantilever based sensors
Senzory na báze nosníkových štruktúr
Registration code:	2/0183/15
Program:	VEGA
Project leader:	Ing. Šoltýs Ján, PhD
Annotation:	Cantilever-based sensors are used for the detection of physical, chemical, and biological analytes. In principle, every external perturbation of magnetic, electrical, thermal, or chemical origin can be transducted into mechanical motion. A cantilever deflection can be measured with extremely high sensitivity and selectivity. The project aims to develop new techniques for modification of commercial scanning force probes and to produce new cantilever-based sensors. The key enabling technology of the novel sensors is focus ion beam ablation and on-chip electron beam lithography. Application of such techniques in cantilever sensing opens new functionalities of the cantilever, which can be used for sensor applications and research purposes in physics and biomedicine.

Thermo-electrical stability of superconductors in unconventional cooling conditions
Tepelno-elektrická stabilita supravodičov pri nekonvenčných spôsoboch chladenia
Registration code:	0061/01/01
Program:	SASPRO
Project leader:	Ing. Vojenčiak Michal, PhD.
Annotation:	Superconductors are materials with strongly non-linear current-voltage characteristic. When the transported electrical current is below the critical value they exhibit zero resistance, while at higher currents their resistance is high. Latter regime is associated with energy dissipation and temperature increase; it can lead to the temperature excursion causing a damage of superconducting material. Stability of the superconducting wire describes how big is the margin against transition to nonsuperconducting state and whether it will be followed by a material degradation. In this project we investigate the stability in conditions representing the situation typical for two configurations: the fault current limiter and the cable for a coil winding.
