Abstract

A pulse technique, which eliminates errors due to large offset voltages, has been devised to measure the Seebeck coefficient in high resistivity materials. Measurements of the Seebeck coefficient of Li:MgO have been made between 25 and 1000°C. Li:MgO is a p-type material, and the position of the Fermi level is ~3.1 eV above the valence band. Under appropriate conditions, sample resistance can be determined from the time dependence of the temperature gradient and Seebeck voltage pulses.
