Simultaneous infrared transmission and laser light scattering experiments on GaAs grown by the liquid encapsulated Czochralski technique are reported. Low-temperature photoquenching experiments are employed to demonstrate in a direct way that the nonuniform infrared images of large diameter GaAs crystals arise from absorption rather than scattering processes.

    The high-pressure liquid encapsulated Czochralski growth of indium lattice-hardened GaAs, from 3 kg melts, has resulted in low-dislocation, large-diameter crystals which exhibit thermally stable, semi-insulating properties. Post-growth boule annealing is found to be an effective stress-relief...

    The amount of carbon in GaAs and (Al,Ga)As films depends on the orientation of crystals grown by metalorganic chemical vapor deposition. We investigated the relation between the incorporation of carbon and the orientation of crystals using (100), (311)A, and (311)B substrates. The concentration...
