Precipitation in low temperature grown GaAs
The precipitation of arsenic in GaAs epitaxially grown at low temperature (LT GaAs) has been studied as a function of the post-growth annealing temperature by three independent methods: transmission electron microscopy (TEM), Raman scattering, and for the first time [...]
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 [...]
