Evaluation of physical parameters for the group III nitrates: BN, AlN, GaN, and InN

Estimation of dielectric, optical, electrooptical, magnetic, elastic, photoelastic, piezoelectric, and phonon characteristics of XN (X=B, Al, Ga, In) crystals is performed by simple methods using quantum-mechanical and semiempirical approaches. The values of deformation potentials and magnetic susceptibilities are determined. The results of calculations are compared with the available experimental data and the calculations of other authors.
