Surface-Diffusion of in on Ge(111) Studied by Optical 2nd-Harmonic Microscopy
Surface diffusion of In on Ge(111) has been measured by optical second harmonic microscopy. This technique employs surface second harmonic generation to directly image submonolayer surface concentration profiles. The coverage dependence of the diffusivity D can then be obtained from a Boltzmann-Matano analysis. In the coverage range 0.1
