The modifications of microhardness and edge absorption curves, increases in a number of radiative recombination centers has been associated with laser stimulated dissociation of the region rich of impurities, generation of defects and their interaction with intrinsic defects.enmonocrystalCzochralski methodlaserspectrumArticle
