Tetrahedrally-bonded materials, such as silicon, diamond, or gallium nitride, are characterized by a low coordination number of 4 in the crystalline phase and, in general, can exhibit a liquid phase with higher density and coordination. This leads to

Photoemission spectra recorded near the Ga 3p photothreshold from GaN have been found to contain satellites of the main Ga 3d emission line. The intensity of these satellites resonate at this threshold, and are associated with a 3d(8) state. The corr

GaN single crystals exhibiting the lowest dislocation density (below 100/cm 2 ) are grown at high hydrostatic N 2 pressures of 10-20 kbar. Despite small dimensions of such crystals (up to 1/2) they offer a unique chance to construct high power laser
