Vibrational spectroscopy of hydrogenated GaP1−yNy

The N and H vibrational modes in hydrogenated GaP1-yNy have been studied by infrared absorption spectroscopy and density-functional theory. Data for samples containing both H and D show that the dominant defect complex contains two weakly coupled N-H stretching modes. Theory predicts an H-N-H comple...

Summary:The N and H vibrational modes in hydrogenated GaP1-yNy have been studied by infrared absorption spectroscopy and density-functional theory. Data for samples containing both H and D show that the dominant defect complex contains two weakly coupled N-H stretching modes. Theory predicts an H-N-H complex with C1h symmetry whose vibrational properties are in agreement with experiment. Experimental and theoretical results are remarkably similar to those found previously for GaAs1-yNy.
