Description

The crystallographic and microstructural characteristics of liquid phase epitaxy lattice-matched InxGa(1-x)AsySb(1-y)/GaSb (100) heterostructures is presented. Using both transmission electron microscopy and high resolution X-ray diffraction, a variety of diffusional based phase transformations in the epitaxial films are observed, including: spinodal decomposition, compositional modulations of the order of 30 nm, and weak long range ordering. These results are interpreted in terms of the possible influence of substrate surface structure on the phase stability of epitaxial layers
