Query: Strain mediated adatom stripe morphologies on Cu<111> simulated   Substrate strain mediated adatom configurations on Cu<111> surfaces have been
simulated in a coverage range up to nearly 1 monolayer. Interacting adatoms
occupy positions on a triangular lattice in two dimensions. The elastic
interaction is taken from earlier calculations, short range effects are added
for comparison. Dependent on the coverage different morphologies are observed:
Superlattices of single adatoms in the 0.04 ML region, ordered adatom clusters
in the 0.1 ML region, elongated islands in the 0.3 ML region, and interwoven
stripes in the 0.5 ML region. In the region above the sequence is reversed with
occupied and empty positions complemented. Stronger short range interactions
increase the feature size of the clusters and reduce their lattice order. The
influence of the substrate elastic anisotropy turns out to be significant.
Results are compared with morphologies observed on Cu<111> surfaces and the
applicability of the model is discussed.
