Microwave Measurement of the Negative Differential Mobility in N-GaAs.

Abstract

The negative differential mobility in bulk n-GaAs was measured using microwave techniques. Measurements were made both at room temperature and at temperatures below room temperature for samples of n-type GaAs having different low-field mobilities and doping densities at room temperature. The average conductivity of the sample when subjected to different peak r-f electric fields was measured and the instantaneous conductivity deduced by solving an integral equation. (Author)
