A MONTE-CARLO STUDY OF STOCHASTIC GROWTH ON THE AU(110) (1X2) SURFACE- SIMULATION OF HELIUM SCATTERING DURING GROWTH

Simulations are presented for a model of growth on the Au(110) surface . We use the Monte Carlo method in the stochastic deposition mode and also at finite temperatures. We show how the initial missing row (1 x 2) superstructure of the substrate disappears during growth. Helium sc attering spectra simulated in a kinematical approximation are shown to reflect the evolution of the surface. Direct numerical simulations of the correlation function versus coverage and distance parallel to the surface are shown. Their analysis, as well as that of peak shapes wit hin the Gaussian approximation, allow us to estimate the effective exp onents cc and beta that characterize the time and space scaling laws.
