摘要：

Detailed infrared studies performed on GaP samples weakly doped with nitrogen and hydrogen have been performed. A trigonal defect involving nitrogen and a pair of nonequivalent hydrogen has been identified, with local vibrational modes at 2885.5, 2054.1, and 1049.8 cm(-1) for the N-14 related complex. N-14-N-15 isotopic shifts have been observed for the two high wave number modes. All of these modes are attributed to a defect with one hydrogen in bond centered and the other one in antibonding positions around nitrogen. The two hydrogen atoms are bonded mainly to the same nitrogen atom.
