Query: Modelling (001) surfaces of II-VI semiconductors   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 CdTe(001) surface to a local (2x1) arrangement
of the Cd atoms as an equilibrium phase transition. Its analysis by means of
transfer-matrix and Monte Carlo techniques shows that the small energy
difference of the competing reconstructions determines to a large extent the
nature of the different phases. Then, this lattice gas is extended to a model
of a three-dimensional crystal which qualitatively reproduces many of the
characteristic features of CdTe which have been observed during sublimation and
atomic layer epitaxy.
