Description
ZnO (wurtzite) samples were implanted with Ar+ ions to generate intrinsic defects within the samples for fluencies ranging from 10^4 to 10^18 per cm. Doppler broadening of the annihilation centroids were obtained to determine S- and W - parameters which are associated with a quantity of defects. X-ray diffraction (XRD) method was employed to determine any structural or phase change associated with Ar+ implantation. The positron annihilation spectroscopy results were correlated with Optical absorption spectra of the crystals to investigate various bands at different fluencies.
