CRYSTAL OF NITRIDE OF GROUP-13 METAL ON PERIODIC TABLE, AND METHOD FOR PRODUCING SAME

摘要

The present invention addresses the problem of providing: a crystal of a nitride of a Group-13 metal on the periodic table, which has good crystallinity and has no distortion; and a method for producing the crystal. The crystal of a nitride of a Group-13 metal on the periodic table according to the present invention contains oxygen atoms and hydrogen atoms and has a ratio of the oxygen concentration to the hydrogen concentration of 0.5 to 4.5.
