Origin of the 1. 59-eV luminescence in ZnTe and the nature of the postrange defects from ion implantation
We describe constituent-vapor heat-treatment experiments on ZnTe which indicate that the 1.59- eV luminescence in this material is V/sub Zn/ -related. The effects of Ga or I doping suggest further that the band is associated with some species of V/sub Zn/ -donor complex. This understanding of the 1.59- eV luminescence provides additional insight into our earlier study of postrange-defect introduction in ion-implanted ZnTe. The observed survival of the incumbent 1.59-eV band in the postrange zone is discussed in relation to the conclusion from earlier published studies that Zn/sub i/ are the dominant postrange defects in ZnTe. We conclude that Zn/sub i/ are not strongly involved in the observed postrange damage. To the contrary, our work gives some indication that V/sub Zn/ - and/or V/sub Te/ -related centers are formed in the postrange zone.
