Perovskitovské tenké vrstvy a štruktúry vhodné pre modern elektroniku a senzoriku
Perovskite thin films and structures for modern electronics and sensorics
Program: VEGA
Project leader: RNDr. Španková Marianna PhD
Annotation: We prepare different types of perovskite films -ferromagnetic, superconducting, dielectric- (thickness up to 100nm) and micro- and nano structures. YBa2Cu3Ox superconducting microstrips will be irradiated by electrons (30keV) with the aim to create channels for easy vortex motion. We also focus on detailed study of Si/dielectric layerinterface using unconventional materials (SrO, TiN) with the aim to enable epitaxial growth of buffer layersnecessary for realization of uncooled microbolometers on the base of La0.67Sr0.33MnO3 films working and atfrequencies in THz range. Beside the Bi4Ti3O12 studied so far different types of other buffer layers will be testedin order to develop new types of bolometers. We continue in study of perovskite superconductor S/ferromagnet Fand S/F/S structures with the aim to resolve the phenomenom of S/F thin films interaction (proximity effect). Theimplementation of pi-type Josephson junction in digital and quantum circuits may solve some problems of superconducting qubits.

MOSSLE – Modifikácia YBCO tenkovrstvových štruktúr nízkoenergetickými elektrónmi pre supravodivú elektroniku
Modification of YBCO thin film structures using low energy electron beam processing for superconducting electronics
Program: SRDA
Project leader: Ing. Chromik Štefan DrSc.
Annotation: The proposed project deals with the effect of low energy electron irradiation of YBCO microstrips with the aim to fabricate channels for easy vortex motion. Detailed analyses will be focused on the subtle balance of many processes involving kinetic (kick-off) process, thermal activation of oxygen as well as ordering of Cu-O chains by incident electrons. The study of these phenomena together with the effect on introducing of artificial pinning in the illuminated channels, having influence on the dynamics of the vortices in the channel, lead to the contribution to basic reserach and also to the realization of functional model structure for the application in superconducting electronics.
