Hot Electron Polar Scattering in InSb

Abstract

Abstract The energy and momentum relaxation of conduction electrons by optical phonons in InSb are studied using the energy band structure calculated by Kane. For simplicity, the drifted Maxwellian approach is used and its form for an arbitrary band structure is presented. No intrinsic breakdown is obtained. On the contrary, the model gives a voltage‐controlled differential negative mobility for high fields.
