Abstract

We describe the design and operation of a simple apparatus for the measurement of the thermoelectric power under pressure. Its performance has been optimized especially for low thermal conductivity solids such as organic quasi-one-dimensional conductors, and it may be used with a pressure medium that is in either the solid or liquid state. These materials have an absolute thermopower of the order of magnitude of ten μV K^-1 at ambient temperature. The uncertainty of the apparatus is about 5% and its sensitivity considerably better. Measurements have been made from 300 to 2 K and 0 to 25 Kbar.
