Superconducting THz sources with 12% power efficiency
R. Cattaneo, E. A. Borodianskyi, A. A. Kalenyuk +1
Low power efficiency is one of the main problems of THz sources, colloquially known as the THz gap. In this work we present prototypes of THz devices based on whisker-crystals of a…

Influence of the Fermi surface geometry on a Josephson effect between an iron-pnictide and conventional superconductors
A. A. Kalenyuk, E. A. Borodianskyi, A. A. Kordyuk +1
We study Josephson junctions between a multi-band iron-pnictide Ba1-xNaxFe2As2 and conventional s-wave superconductors Nb and Cu/Nb bilayer. We observe that junctions with a Cu int…
