In this paper, work is reported on the growth of GaInAs/InP by chloride vapour phase epitaxy (VPE) by varying the Ga:ln source alloy composition to obtain lattice-matched epilayers. The epilayers of Ga1-xInxAs (x < 0.35)/GaAs and GaAs/Ge were grown by metal organic vapour phase epitaxy (MOVPE). Surface morphology, lattice mismatch, electrical and optical characterization was carried out to evaluate the quality of the layers.
