Thermal and Electronic Transport Properties of Single Crystal PtSb₂ Obtained by the Photoacoustic Method

Abstract

Single crystal PtSb 2 ingots were synthesized using the Bridgman technique. Electronic transport properties and thermal diffusivity of PtSb 2 sample were determined using the photoacoustic (PA) method with transmission detection configuration. The excess carrier lifetime, the recombination velocity and thermal diffusivity were determined by comparing the experimental results and theoretical photoacoustic signals.
