Metalorganic Molecular Beam Epitaxy of Zn1-xCdxSySe1-y Quaternary Alloys on GaAs Substrate

Abstract
The successful growth of Zn1-x Cd x S y Se1-y (ZnCdSSe) quaternary alloys by metalorganic molecular beam epitaxy (MOMBE) is reported. Layer-by-layer growth was confirmed for the first time by monitoring the intensity oscillation of a specular beam in a reflection high-energy diffraction (RHEED) pattern. ZnCdSSe layers coherently grown on GaAs exhibited good crystallographic and optical properties.
