Electronic Structure and XANES Calculations of Silicate Compounds

Abstract

We estimated surface energies of all flat surfaces of forsterite within the framework of density functional theory. We found that surface energy of (120) surface is the lowest and those of (010), (130) and (112) surfaces are followed subsequently. Morphology of forsterite at 0 K is predicted. Calculated Si K-edge XANES spectra of silicon in forsterite are consistent with experiments.
