Abstract

We studied the effect of group V switching times on the formation of interfacial layers in InGaP/GaAs heterostructures grown by LP-MOCVD using low temperature photoluminescence (PL), double crystal X-ray diffraction (DCXRD) and high resolution transmission electron microscopy (HRTEM). Due to the severe substitution process of P by As, the quality of InGaP-to-GaAs interface was very sensitive to switching times. By optimizing the switching conditions, we were able to minimize the interfacial layers to one monolayer (ML) of In _0.5 Ga _0.5 As at the GaAs-to-InGaP interface and 1 ML of In _0.65 Ga _0.15 P _0.15 As _0.85 at the InGaP-to-GaAs interface. Heterojunction bipolar transistors (HBTs) grown using this switching scheme showed excellent etch selectivity as well as dc characteristics.
