Short range order in amorphous and liquid Se1−xTex systems

摘要: Abstract In this paper we present a study of local order in amorphous and liquid SeTe systems. The first part is neutron scattering the Selenium state at room temperature from melting point up to 900 C. Se 1−x Te x mixtures are studied 40% atomic Tellurium 100% Tellurium. pair correlation function clearly emphasizes importance covalent bonding divalence very sharp 1st 2nd peaks even high temperatures 50% Hence second deal with quasi-crystalline model already used for A generalization calculation binary systems provides us fair simulation structure factors. For lowest concentrations short range seems be mainly substitutional, as far chains concerned. By increasing concentration 3-valency produces chain branching which distorts Selenium-like structure.
