On the Hot Electron Effect in n-Type Germanium

Abstract

The variation of the mobility with an applied electric field is calculated on the assumption that interelectronic collisions are predominant. The scattering of electrons by acoustic and by non-polar optical modes of lattice vibrations is considered without the restriction, previously imposed, that the latter is only effective when the moan electron energy is greater than the phonon energy. Good agreement between the theory and experiments is obtained without the use of arbitrary parameters.
