Defect structure and optical properties of alkaline-earth fluorides

Shi, Hongting 25 May 2007 (has links)
I present and discuss the results of calculations ofelectronic structures of perfect and defective CaF2 and BaF2 crystals. These are based on the ab initio Hartree-Fock method with electron correlation corrections and ondensity-functional theory calculations with different exchange-correlation functionals, including hybrid exchange techniques.The defective systems include F centers, M centers, O-V dipoles, Hydrogen impurities and H centers.
