Title: Experimental and Theoretical Insights into the Structure of Tellurium Chloride Glasses

Abstract

Here, the structure of the binary chalcohalide glasses Te1-xCLx (0.35 <= x <= 0.65) is considered by combining experimental and theoretical results. The structural network properties are influenced by a competition between ionic and covalent bonding in such glasses. At first, a focus is placed on the detailed information available by using the complementary high-energy X-ray and the neutron diffractions in both the reciprocal and real spaces. The main characteristic suggested by the structure factors S(Q) concerns the presence of three length scales in the intermediate range order. The total correlation function T(r) lets us also suppose that the structure of these glasses is more complicated than Te-chain fragments with terminal Cl as demonstrated in crystalline Te3Cl2. Molecular dynamics simulations were subsequently performed on Te3Cl2 and Te2Cl3, and coupled with the experimental data, a highly reticulated network of chalcogen atoms, with a fair amount of chlorine atoms bonded in a bridging mode, is proposed. The simulations clearly lead to a glass description that differs markedly from the simple structural model based on only Te atom chains and terminal Cl atoms. Solidstate NMR experiments and NMR parameters calculations allowed validation of the presence of Te highly coordinated with chlorine in thesemore » glasses.« less

Figure 1 Figure 1: Dependence of the density, d (black squares), and the glass transition temperature, Tg (grey circles) as a function of chlorine atomic content x. The density of amorphous tellurium is also plotted (empty red square) to underline the linear evolution of the density of the glasses.
