The use of an InP epitaxial layer grown at low temperatures before the growth of a step-graded InAsP metamorphic buffer has been shown to provide a large improvement in the crystal quality of the final metamorphic layer. The improvement is evidenced by over an [...]

The dependence of the morphology and crystallinity of an amorphous Ge (a-Ge) interlayer between two Si wafers on the annealing temperature is identified to understand the bubble evolution mechanism. The effect of a-Ge layer thickness on the bubble density and size at different annealing [...]

M-Plane GaN Grown on m-Plane Sapphire by Hydride Vapor Phase Epitaxy
M-plane GaN epilayers have been directly grown on m-plane sapphire substrates by hydride vapor phase epitaxy using a low temperature GaN nucleation layer. The m-plane GaN surface is optically smooth and mirror-like, with rms [...]
