✦ Synopsis

We report a study of the structural and electronic properties of cubic nitride-superlattices using a ÿrst-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 (AlN)1(GaN)1; (InN)1(GaN)1 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.
