摘要
Scanning tunneling microscopy (STM) has been used to investigate the effect of the deposition rate on the resulting morphology of GaAs(001)-(2 X 4) surfaces grown by molecular beam epitaxy. Low deposition rates (0.2 mu m/h) are found to create smooth surfaces and lead to anisotropic islanding with average length ratios of A steps to B steps which are measurably larger than those produced by standard deposition rates (0.7 mu m/h). For each growth rate, the mean-square-height fluctuation function has been calculated in order to characterize the surface roughness observed with STM and the anisotropy associated with the roughness.
