Abstract

Epitaxial layers of GaAs and GaAsxP1−x were deposited under a variety of conditions using a remote plasma in a metal-organic chemical vapor deposition (MOCVD) reactor. The remote rf plasma dissociated AsH3 and PH3 into highly reactive radicals increasing the growth rate at low temperatures and increasing the phosphorus incorporation at temperatures below 850° C. GaAsxP1−x with a high P content could be grown at low deposition temperatures by using the plasma to increase the reactivity of PH3. The growth rate of both GaAs and GaAsxP1−x was increased at low temperatures and GaAsxP1−x was grown at temperatures down to 550° C.
