  Structure and vibrational modes of AgI-doped AsSe glasses: Raman scattering and ab initio calculations

  摘要：

  We report an investigation of the structure and vibrational modes of (AgI)(x) (AsSe)(100-x), bulk glasses using Raman spectroscopy and first principles calculations. The short- and medium-range structural order of the glasses was elucidated by analyzing the reduced Raman spectra, recorded at off-resonance conditions. Three distinct local environments were revealed for the AsSe glass including stoichiometric-like and As-rich network sub-structures, and cage-like molecules (As4Sen, n=3, 4) decoupled from the network. To facilitate the interpretation of the Raman spectra ab initio calculations are employed to study the geometric and vibrational properties of As4Sen molecular units that are parts of the glass structure. The incorporation of AgI causes appreciable structural changes into the glass structure. AgI is responsible for the population reduction of molecular units and for the degradation of the As-rich network-like sub-structure via the introduction of As-I terminal bonds. Ab initio calculations of mixed chalcohalide pyramids AsSemI3-m provided useful information augmenting the interpretation of the Raman spectra. (C) 2010 Elsevier Inc. All rights reserved.

• Phase equilibria and glass formation in the AsSe-MnSe system

  The phase equilibrium in the AsSe-MnSe system has been studied using physicochemical characterization techniques (differential thermal analysis, X-ray diffraction, microstructural analysis, microhardness tests, and density measurements), and its phase diagram has been mapped out. The system is shown to be a pseudobinary join of the ternary system Mn-As-Se. At AsSe: MnSe = 1: 1, the system contains a compound of composition MnAsSe(2), which melts incongruently at 750A degrees C. The glass-forming region extends to 15 mol % MnSe. We have examined the crystallization behavior of the glasses. Solid AsSe dissolves up to 2 mol % MnSe, and solid MnSe dissolves up to 2.5 mol % AsSe.

  The solid-phase equilibria and thermodynamic properties of an As–Se system are studied using the electromotive force (EMF). The existence of compounds As2Se3, AsSe, and As4Se3 in a system with near constant composition is confirmed. The relative partial molar functions, standard Gibbs free energies, enthalpies of formation, and standard entropies of As in the alloys are calculated using EMF measurements
