摘要：
An analytical model of the energy distribution of hot electrons in semiconductors derived under the simplifying assumptions of a single nonparabolic conduction band, small space derivative of the external electric field, and emission of optical phonons as dominant energy loss mechanism is presented. The model, indicating that band nonparabolicity makes the electron energy distribution to deviate markedly from the Maxwellian low-field case, is shown to be substantially applicable to the case of silicon MOSFET’s by means of comparisons with Monte Carlo simulations. © 1990 IEEE
