Giant nonlinearity of kinetic inductance in superconducting hybrid strip
D. Yu. Vodolazov, Yu. P. Korneeva, M. A. Dryazgov +6
We demonstrate giant nonlinearity of the kinetic inductance in a superconducting NbN/Al hybrid strip. In contrast to ordinary superconductors, where the maximum observed curr…

4-Pixel NbN Hot-Electron Bolometer Integrated in a SiN Planar Optical Waveguide with On-Chip Fiber-Alignment Trench
N. A. Vovk, G. A. Matveev, M. A. Mumlyakov +7
In this work, we design and characterize a 4-pixel superconducting hot-electron bolometer (HEB) based on niobium nitride (NbN), integrated with individual planar silicon nitride (S…

Molybdenum low resistance thin film resistors for cryogenic devices
Yu P Korneeva, M A Dryazgov, N V Porokhov +4
We present a study of thin-film molybdenum resistors for NbN electronics operating at cryogenic temperatures. The key step is the 0.5-1.5 keV ion cleaning-activation of NbN before…
