Additional Description

Abstract

An experimental study of a reflection cavity scheme used to measure changes in the conductivity of semiconductor samples is presented. The germanium sample with associated microwave circuitry acts as a highly sensitive system where by in the null condition almost complete absorption occurs. Changes in conductivity from the null point will cause a sharp increase in reflected microwave power. This change in reflected power may be used to measure a change in conductivity, or in a device application would represent the output signal. Calculations indicate that as an infrared photoconductive detector, this microwave effect may be competitive with state-of-the-art components.
