MONTE-CARLO PARTICLE SIMULATION OF A QUANTUM-WELL HETEROJUNCTION FIELD-EFFECT TRANSISTOR - COMPARISON WITH EXPERIMENTAL-DATA

A heterojunction field-effect transistor with a quantum well channel h as been studied using the Monte Carlo particle model. The transport in the channel has been calculated both considering and neglecting the e ffect of energy quantization of the conduction band. The results of th e two approaches were found to agree well with each other and with exp erimental data. The significant differences between classical and quan tum mechanical calculations are the better confinement of the carrier in the channel and the better agreement of the transfer characteristic s with experiment for the latter.
