Phosphorus-containing III-V compounds are the preferred materials for millimeter-wave and submillimeter-wave devices and circuits, optoelectronic devices, and solar cells. InGaP lattice matched to GaAs has a direct band gap of 1.9eV at room temperature, which is a highly efficient light-emitting material. We are pleased [...]

The carrier concentration and thickness of n-type GaAs epitaxial layers were obtained by cell voltage measurements in anodization, and the results are compared with those obtained by differential C-V measurements. The carrier concentrations in the epi-layer are within the order of those obtained by [...]
