Abstract

An apparatus is described to measure the Peltier coefficient (P) at 0°C of materials exhibiting rather large values. The Peltier heat is calculated from volume changes of ice-water mixtures confined at the ends of the sample under investigation. Measurements performed on Bi-Te alloys are compared with Seebeck coefficients (S) using Kelvin's second relation P = ST, where T is the absolute temperature.
