Abstract

This paper presents a detailed mathematical model of the coupled gas-phase chem- istry, surface chemistry, and fluid mechanics in the MOCVD of GaAs from trimethylgallium and arsine in a rotating-disk reactor. The model predicts steady-state deposition rates as a function of susceptor temperature and partial pressure of the reactants. Rate constants in the model have been adjusted to match experimental deposition rates from the literature.
