Abstract

In this paper we consider models for some adsorption effects, the resulting change of the work function at metal-oxide-semiconductor sensitive layers of gas sensors and their implementation in a two dimensional device simulator, which solves the Poisson equation. An example for the application of this simulation program is given with a Suspended Gate Field Effect Transistor.
