Spectroscopic and Morphological Structure of Tetrahedral Oxide Glasses

摘要: Publisher Summary This chapter examines the data on vibrational spectra to distinguish features of an n-dimensional nature, specifically n = 3 (bulk), 2 (internal surface), and 0 (point-defect) modes. It summarizes general spectrum a tetrahedral oxide glass containing O* p,s atoms, without restricting discussion SiO or GeO neutron, infrared, Raman spectra. The aim is present in simplest possible way essential elements freed from irrelevant unnecessary computational details that arise specific force field calculations based ball-and-stick models. reviews 2, obtained CRN models, demonstrates failure these models explain for . presents morphological cluster g-SiO g-GeO shows they are capable explaining s Quantitative results detailed calculation dimensions clusters, their surface textures, interfacial spacing. These tested against wide range found be remarkably consistent with many observed phenomenological trends.
