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

This work explores the strain dependence of the piezoelectric effect in GaAs and InAs zinc blende crystals. We write the polarization in terms of the internal anion-cation displacement and the ionic and dipole charges. We then use ab initio density f

Publikováno v: Physical Review B. 84

Firstand second-order piezoelectric coefficients for all binary group-III nitride (III-N) wurtzite semiconductors are calculated using ab initio density functional theory. The method used allows the simultaneous determination of spontaneous and strai
