Successes and Predictions of a Pseudopotential Approach in Anion-Mixed Nitrides

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 Ga(1-y)In(y)As(1-x)N(x) quaternaries and GaA(0.5-x)P(0.5-x)N(2x) solid solutions.
