چکیده
1. Introduction The stationary behaviour of semiconductor devices is governed by a set of nonlinear elliptic partial differential equations. This includes a nonlinear Poisson equation and two nonlinear continuity equations. Using Gummel's method [2] we can decouple the nonlinear elliptic system so that at each step we solve an equation of the form

Numerical Discretization of Energy-Transport Models for Semiconductors with Nonparabolic Band Structure
The energy-transport models describe the flow of electrons through a semiconductor crystal, influenced by diffusive, electrical and thermal effects. They consist of the continuity equations for the mass and the energy, coupled to Poisson’s equation for the electric potential. These models can be derived from the semiconductor Boltzmann equation. This paper consists of two parts. The first part ...

This paper describes a three{dimensional simulator for semiconductor devices in stationary state developed on a message passing multiprocessor. A Gummel style nonlinear iteration was used, and the Poisson and the continuity equations were discretized using the nite element method. A new iterative scheme was introduced in order to solve the non{linear Poisson equation. The nonsymmetric continuit...

{ In this work we describe a methodology for solving the basic set of state stationary semiconductor device equations. We present a new iterative method for the solution using nite elements of the non linear Poisson equation and use a Conjugate Gradient type method for solving the non symmetric continuity equations.

The stationary energy-transport equations for semiconductors in three space dimensions are numerically discretized. The physical variables are the electron density, the energy density, and the electric potential. Physically motivated mixed Dirichlet-Neumann boundary conditions are employed. The numerical approximation is based on an hybridized mixed finite-element method using Raviart-Thomas el...
متن کاملA new positive definite semi-discrete mixed finite element solution for parabolic equations
In this paper, a positive definite semi-discrete mixed finite element method was presented for two-dimensional parabolic equations. In the new positive definite systems, the gradient equation and flux equations were separated from their scalar unknown equations. Also, the existence and uniqueness of the semi-discrete mixed finite element solutions were proven. Error estimates were also obtaine...
