Popis: In this paper, we show the use of an optimally parameterized empirical potential of the Abell-Tersoff type and demonstrate that we can obtain a deep level of insight into the properties of the epitaxially grown quaternary alloy InGaAsSb. We find that the strain energy as a function of composition does not follow intuitive averages between the binary constituents and that the theoretical behaviour appears to be substantiated by experimental evidence of growth of InAs self-assembled quantum dots capped by GaSbAs.
