Abstract
Measurements of the Seebeck coefficient on samples possessing resistivities between 1012 and 1014 Ω cm are accomplished by establishing a temperature difference between two electric contacts and reading the resulting voltage difference on a sensitive vibrating reed electrometer. Electrostatic pickup (through the ambient and gradient heating systems, the thermocouple leads, or from charges released through contact of the lead wires with a dielectric support) is eliminated in the most sensitive electrometer range by rigorous shielding procedures, which are described. The method was tested by measuring Seebeck coefficients between 30 and 80°C on metallo‐organic ferrocene crystals of 0.5 mm thickness.This publication has 1 reference indexed in Scilit:
