21 April 2006Noise in MgB2 thin film: a candidate material for space-borne infrared detector development
An MgB2 thin film was grown on a SiN-Si substrate, with a superconducting transition temperature, Tc, near 39K. At the mid-point of the transition (T= 38.24K) and at 10Hz a noise spectral density SV = 0.34nV/ √Hz was measured. The temperature noise, Kn, of the MgB2 film at different frequencies is compared to that of cuprate high temperature superconducting (HTS) thin films (with Tc ~ 90 K) used currently in transition-edge bolometers. Κn values predict that high performance far-IR thermal detectors (i.e bolometers) can be developed using MgB2 as a thermistor.
