Paper Abstract

We report on a comparative investigation of as grown and alpha particle irradiated Ga-As-nipi doping super-lattices. We have used inelastic light scattering and low temperature photoluminescence spectroscopy to study the change in structural as well as electronic properties. Depending on the dose of alpha particles, we have found that the degree of structural damage varies. The PL spectroscopy shows that the main, e-Zn(h), band shifts toward higher energy (with a decrease in intensity). After annealing, partial recovery is found.
