Me. Kompan et al., Polarization-dependent inhomogeneous broadening of the edge luminescence band of hexagonal gallium nitride, PHYS SOL ST, 42(6), 2000, pp. 1041-1044
A correlation of the shape of the edge luminescence band for hexagonal gall
ium nitride and the polarization of exciting light is revealed. The effect
is explained by the existence of microregions with different directions of
deformation in the plane perpendicular to the sixfold axis. (C) 2000 MAIK "
