An Impact Ionization Model Including Non-Maxwellian and Non-Parabolicity Effects
Accurate modeling of impact-ionization is a critical issue for submicron devices. It is well known that models based on the electric field or on the average carrier energy give a rather poor description of the problem. We show that by accounting for the average square energy an accurate analytical description of the distribution function can be given which can then be used to evaluate microscop...
متن کاملNon-Parabolicity and Non-Maxwellian Effects on Gate Oxide Tunneling
Simulation of gate oxide tunneling currents in subquartermicron devices requires correct modeling of the electron energy distribution function in the channel region. However, the common assumption of a heated Maxwellian distribution function leads to a dramatic overestimation of the high-energy tail of the distribution function near the drain region which leads to spurious gate currents for sho...
متن کاملFrom kinetic theory to dissipative fluid dynamics
We present the results of deriving the Israel-Stewart equations of relativistic dissipative fluid dynamics from kinetic theory via Grad’s 14-moment expansion. Working consistently to second order in the Knudsen number, these equations contain several new terms which are absent in previous treatments.
متن کاملGeneralized Kinetic Theory of Electrons and Phonons
A Generalized Kinetic Theory [1] was proposed in order to have the possibility to treat particles which obey a very general statistics. By adopting the same approach, we generalize here the Kinetic Theory of electrons and phonons. Equilibrium solutions and their stability are investigated. 1. Introduction Very recently [1], a Generalized Kinetic Theory (GKT) has been proposed by Rossani and Kan...
متن کاملImpurity in a Maxwellian unforced granular fluid.
We investigate velocity statistics of an impurity immersed in a uniform granular fluid. We consider the cooling phase, and obtain scaling solutions of the inelastic Maxwell model analytically. First, we analyze identical fluid-fluid and fluid-impurity collision rates. We show that light impurities have similar velocity statistics as the fluid background, although their temperature is generally ...
