Abstract

The construction and the parameters of a new-strain dependent empirical pseudopotentials method are described and provided, respectively. This method is shown to reproduce with a very high accuracy some observed unusual properties in various complex anion-mixed nitride alloys. This method is also used to predict and understand anomalous effects that remain to be experimentally discovered in Ga1−yInyAs1−xNx quaternaries and GaAs0.5−xP0.5−xN2x solid solutions.
