Abstract:

We have developed an in situ technique for determining the group-V composition in gas-source molecular beam epitaxy GSMBE growth of mixed group-V compounds, such as GaAsP, InAsP, and InGaAsP. The in situ technique consists of monitoring the intensity oscillations of group-V-induced reflection high-energy electron diffraction RHEED. We have grown high-quality InAsPInP strained- layer superlattices with exciton emission at 1.06, 1.3, or 1.55 microns, suitable for long-wavelength modulator applications. We have also explored the capability of GSMBE by investigating low-temperature-growth InP and p-type carbon doping in In0.5Ga0.5As and In0.5Ga0.5P.
