Heat Pulse Propagation Characteristics in N-Type InAs.
Abstract
Heat-pulse measurements have been performed between 1.6 K and 4.2 K on degenerate n-type InAs single crystals of various concentrations. In this temperature range the propagation of phonons is ballistic. Constantan thin films were used as heaters and measurements were made for power inputs between 0.04 watts/sq mm and 50 watts/sq mm. Superconducting granular aluminum thin films or gold seeded tin thin films were used as bolometers for detection of the heat pulses. The results are compared with the earlier results in InSb.
