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 [...]

Experimental and theoretical investigation of phosphorus in-situ doping of germanium epitaxial layers
We investigate phosphorus in-situ doping characteristics in germanium (Ge) during epitaxial growth by spreading resistance profiling analysis. In addition, we present an accurate model for the kinetics of the diffusion in the in-situ [...]
Highlights
•Nanoscale defects in III–V materials, grown over Si were characterized with CAFM.
•The defects exhibit higher conductivity.
•The contact rectifying feature is hide by a larger current under the reverse bias.
•Patterned samples fabricated using Aspect Ratio Trapping were also characterized.
Abstract
The implementation of high mobility devices requires [...]

Several types of GaN MOSFETs with normally-off operation have been fabricated on insulating substrate and evaluated. In recessed-gate GaN MOSFET, the threshold voltage (Vth) can be easily controlled, but the current drivability is modest and needs to be improved by adopting appropriate device structure [...]
