A method for growing a crystalline composition, the first crystalline composition may include gallium and nitrogen. The crystalline composition may have an infrared absorption peak at about 3175 cm'1, with an absorbance per unit thickness of greater than about 0.01 cm'1. In one embodiment, the composition ay have an amount of oxygen present in a concentration of less than about 3xlO18 per cubic centimeter, and may be free of two-dimensional planar boundary defects in a determined volume of the first crystalline composition. |
