Abstract
A method for the accurate measurement of the thermal resistance of rather thin samples of high heat conductivity is described. It involves a sandwich arrangement in which the thin sample is held between two thicker pieces of bismuth telluride. The thermal resistance of the sandwich is then found by Harman's technique, using the Peltier effect to establish a temperature gradient. The method has been tested experimentally for silicon at room temperature.Keywords
