Experimental study of superconducting transition in a molybdenum–copper thin film structure showing the proximity phenomenon and the estimation of the sensitivity of TES bolometers on the basis of such a structure

A design analysis of imaging radiometer with antenna-coupled transition-edge sensors

“…[6,7], the extra weakening of the electron-phonon interaction is assumed via Andreev electron-reflection effect at the interface between the submicron-size absorber and leads of the antenna made from a higher-T c superconductor (Nb). For our Mo/Cu absorber (T c ¼ 0:1-0:3 K) [8] operating within its superconductor transition region, the RF current from antenna is assumed to be the source of hot electrons within the absorber, and the goal of producing bolometers with NEP % 10 À18 W Hz 1=2 and below can be reached.…”
