Abstract
We have grown GaAs on Si (100) substrates misoriented 4° from the [110] direction using a KrF pulsed excimer laser-assisted Molecular Beam Epitaxy. In this work, we report the systematic study of 2000 A GaAs films grown on Si using a two step growth sequence. Raman scattering, Rayleigh scattering, near band edge photoluminescence, cross-sectional TEM microscopy, in situ RHEED, and optical surface roughness profiles are used to characterize the differences between laser irradiated and non-irradiated areas of the samples. We find a reduction of defects, an enhancement of photoluminescence intensity, and no evidence for laser-induced melting for power levels of up to 25 MW/cm2. Photoluminescence linewidths at 4.5K are comparable to widths observed for 1 micrometer thick GaAs films grown on Si.
