Query: Modelling sublimation and atomic layer epitaxy in the presence of
  competing surface reconstructions   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. Depending on temperature and particle flux, this
model displays surface reconstructions similar to those of (001) surfaces of
II-VI semiconductors. We show, that our model qualitatively reproduces mamy of
the characteristic features of these materials which have been observed during
sublimation and atomic layer epitaxy. We predict some previously unknown
effects which might be observed experimentally.
