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…
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…
Modelling sublimation and atomic layer epitaxy in the presence of competing surface reconstructions
M. Ahr, M. Biehl
We present a solid-on-solid model of a binary AB compound, where atoms of type A in the topmost layer interact via anisotropic interactions different from those inside the bulk. De…
A lattice gas model of II-VI(001) semiconductor surfaces
Michael Biehl, Martin Ahr, Wolfgang Kinzel +2
We introduce an anisotropic two-dimensional lattice gas model of metal terminated II-IV(001) seminconductor surfaces. Important properties of this class of materials are represente…
The influence of the crystal lattice on coarsening in unstable epitaxial growth
M. Ahr, M. Biehl, M. Kinne +1
We report the results of computer simulations of epitaxial growth in the presence of a large Schwoebel barrier on different crystal surfaces: simple cubic(001), bcc(001), simple he…
