LOCAL VIBRATIONAL-MODE SPECTROSCOPY OF NITROGEN-HYDROGEN COMPLEX IN ZNSE

Using infrared and Raman spectroscopy, we have observed two local vibrational modes related to H bonded to N accepters in ZnSe samples grown by metalorganic vapor phase epitaxy. We assign the new mode seen at 3194 cm(-1) to a N-H stretching vibrational mode and tentatively assign the mode found at 783 cm(-1) to a N-H wagging vibrational mode. Polarized Raman spectroscopy was used to determine that the symmetry of the defect complex is C-3 v, which implies that the H atom is in either a bonding or antibonding position.
