INJECTED ELECTRON-HOLE PLASMA PROPAGATION VELOCITY AND LIFETIME MEASUREMENTS IN P-TYPE INDUS ANTIMONIDE

摘要

A finite time is required to complete the injection of as electron-hole plasma throughout the length of a sample of Insb-Upon application of an electric field across the sample ends, a cloud of electron-hole plasma forms at the negative contact and progresses down the sample length past two pairs of biased double probes which are spaced a known distance apart. As the front passes a probe pair t produces a decrease in resistance between the pair. This passage is observed as a pulse on a high speed oscilloscope.
