Flat (001) surfaces of II-VI semiconductors: A lattice gas model
M. Ahr, M. Biehl
We present a two-dimensional lattice gas with anisotropic interactions which model the known properties of the surface reconstructions of CdTe and ZnSe. In constrast to an earlier…
Modelling (001) surfaces of II-VI semiconductors
M. Ahr, M. Biehl, T. Volkmann
First, we present a two-dimensional lattice gas model with anisotropic interactions which explains the experimentally observed transition from a dominant c(2x2) ordering of the CdT…
Kinetic Monte Carlo Simulations of dislocations in heteroepitaxial growth
F. Much, M. Ahr, M. Biehl +1
We determine the critical layer thickness for the appearance of misfit dislocations as a function of the misfit between the lattice constants of the substrate and the adsorbate fro…
Particle currents and the distribution of terrace sizes in unstable epitaxial growth
M. Biehl, M. Ahr, M. Kinne +2
A solid-on-solid model of epitaxial growth in 1+1 dimensions is investigated in which slope dependent upward and downward particle currents compete on the surface. The microscopic…
