Abstract

Longitudinal hot electron drift velocity in n-Hg0.8Cd0.2Te in the extreme quantum limit has been investigated at low temperatures using displaced Maxwellian approximation. The model includes various complexities such as band nonparabolicity, quantum screening due to magnetic quantization, and Landau level broadening due to impurity fluctuations. The influence of alloy scattering on the drift velocity has been examined. The field dependences of hot electron drift velocity in n-Hg0.8Cd0.2Te have also been studied.
