Growth of InP and InGaAsP (E g≥1.15 eV) layers by liquid phase epitaxy under phosphorus overpressure

Abstract
A method is presented for the liquid phase epitaxial growth of stoichiometric InP and InGaAsP (Eg⩾1.15 eV) epitaxial layers by creating a phosphorus overpressure in the growth ambient. The effectiveness of the method and the stoichiometry of InP layers can be monitored with the photoluminescent spectra of a phosphorus vacancy‐impurity complex.
