Claim 0:
1. A gallium-containing nitride crystal comprising:
a gallium-containing nitride in a substantially wurtzite structure comprising an n-type dopant;
impurities of hydrogen [H] and oxygen [O], wherein a ratio of an impurity concentration of hydrogen [H] to an impurity concentration of oxygen [O] is at least 0.3; and
impurities of at least one of Li, Na, K, Rb, Cs, Ca, F, and Cl having an impurity concentration of greater than about 1×1016 cm−3, wherein
a ratio of the impurity concentration of oxygen to an n-type carrier concentration n is between 1.0 and 4.0, and
at wavenumbers between about 3200 cm−1 and about 3400 cm−1, said gallium-containing nitride crystal is essentially free of infrared absorption peaks having an absorbance per unit thickness greater than 0.01 cm−1, as measured by Fourier transform infrared spectrometry (FTIR).
