Abstract
Epitaxial layers of N-doped II-VI semiconductor compounds are grown on GaAs substrates by MOCVD using FME. Separating the growth and doping by alternating introduction of (1) the semiconductor cation and anion and (2) the cation and the dopant increases the level of doping, the level of activation, and the crystal quality.
