The impact-ionization coefficient at high fields is derived in terms of the electric field E and lattice temperature TL, without introducing a priori relations among the parameters. An asymptotic analysis leads to simplifications that validate closed-form expressions of the impact-ionization coefficient.

Abstract

The impact-ionization coefficient at high fields is derived in terms of the electric field E and lattice temperature TL, without introducing a priori relations among the parameters. An asymptotic analysis leads to simplifications that validate closed-form expressions of the impact-ionization coefficient. The role of the relaxation times in determining the slope is discussed, along with the meaning of the critical field.
