Paper Abstract

Using the methods of x-ray double crystal diffraction (DCD) and x-ray DCD topograph as well as photolumincence (n), InGaAsP/InP single heterojunction interface ( SHI) lattice mismatch Influcence on LPE crystal quality is studied. The experimental results indicate that this kind lattice mismatch will lead to impurity condensing, dislocations and defects as well as nonradiation recombination centers increasing in LPE InGaAsP epitax layer and induce composition gradient in the direction of crystal growth.
