Claim 13:
14. The gallium-containing nitride crystal of claim 12, wherein the ratio of an intensity of the cathodoluminescence peak at about 423 nm to the integrated FTIR intensity is between 0.05 and 0.10, where the cathodoluminescence spectrum is measured at room temperature and the intensity is normalized by dividing each individual data point by a total integrated cathodoluminescence intensity between 350 to 900 nm for the spectra and then multiplying by 1000, and the absorbance per unit thickness of the FTIR spectrum is integrated between about 3000 cm−1 and about 3250 cm−1.
