First-principles calculations of the structural and electronic properties of the III-nitrides-based superlattices

We report a study of the structural and electronic properties of cubic nitride-superlattices using a first-principles full potential linearized augmented plane waves method within the local density approximation (LDA). It is shown that the nitrogen atomic positions in the cubic View the MathML source and (InN)1(AlN)1 structures play an important role in the determination of their electronic properties. Such superlattices base group III-nitrides can have better properties than the ternary alloys.
