Two-dimensional hot-electron transport in quantum-well structures of polar semiconductors

Abstract

The drift velocity of hot electrons itinerant two dimensionally in a semiconductor quantum-well structure is calculated at different lattice temperatures on a displaced Maxwellian model. Interactions with deformation potential acoustic and polar optic phonons are considered using the analytic expressions obtained on the basis of a momentum conservation approximation. Contrary to a previous prediction, no negative differential resistance is obtained.
