Optical Spectroscopy of a Nitrogen-Hydrogen Complex in ZnSe

We have observed two local vibrational modes related to H bonded to N acceptors in ZnSe samples. grown by metal organic vapor phase epitaxy. The modes have been seen in both infrared and Raman spectroscopy. The new mode seen at 3194 cm{sup {minus}1} is assigned to an N-H stretching vibrational mode and the mode found at 783 cm{sup {minus}1} is tentatively assigned to an N-H wagging, vibrational mode. Polarized Raman spectroscopy was used to determine that the symmetry of the defect complex is C{sub 3v}, which implies that the H atom is in either a bonding or anti-bonding position
