Abstract
A simple modification of Angstrom's classical method for the determination of the thermal diffusivity of thermoelectric materials is described. Using the Peltier heat generated at the junction of the specimen and a current lead as a periodic heat source, symmetrical temperature variations may be established in the specimen and the diffusivity derived from the propagation constants of the variations. Results of measurements at room temperature on lead telluride are presented.This publication has 1 reference indexed in Scilit:
