Superconducting high-Tc hot electron bolometers used as THz mixers: Predicted performance by hot spot modeling

High-T C hot electron bolometers (HEB) are promising THz mixers due to their expected wide bandwidth, large mixing gain and low intrinsic noise. In this paper, we have simulated the DC characteristics, conversion loss and noise of YBaCuO HEBs with a hot spot model usually dedicated to low-T C device...
