Tungsten thin films can form in one of two crystal structures: alpha (bcc), with a superconducting transition temperature (T/sub c/) of 15 mK, and beta (A15), with a T/sub c/ between 1 and 4 K. Films with intermediate T/sub c/s are composed of both alpha and beta phases. We have investigated how to tune the film T/sub c/ in order to obtain certain values (T/sub c/ /spl sim/ 100 mK) suitable for the fabrication of photon number resolving transition-edge sensor (TES) and arrays of TES detectors… CONTINUE READING
