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 [...]
V-shaped defects in InGaN/GaN multiquantum wells
InGaN/GaN multiquantum well (MQW) structures have been grown on (0001) sapphire substrate by metalorganic chemical vapor deposition. From cross-sectional transmission electron microscopy (TEM), a number of V-shaped defects has been observed on the surface which are associated with mixed [...]
The structures of InxGa1-xAsyP1-y (indium gallium arsenide phosphide) quantum well epitaxially grown on InP substrate can be purchased or customized from PAM-XIAMEN. By adjusting the composition of x and y, the coverage wavelength range is from 870nm (GaAs) to 3.5um (InAs), which includes the optical [...]
