Extending the limits of experimental structure determination of amorphous substances - the Ge-As-Se system

Abstract: Ge-As-Se glasses are interesting for two main reasons: they are widely used in infrared optics and optoelectronics and they serve as model materials for theories of glass formation and stability (e.g. bond constraint theory). Therefore, detailed knowledge of their short range order is important both for applications and fundamental glass science/statistical physics. The main question is whether there are strong chemical correlations in these glasses (preferred bond types, e. g. Ge-Se bonds are more likely formed than Ge-Ge and Se-Se ones) or they can be described as random networks. Recently published experimental studies do not give a clear answer to this problem. The aim of our research is to determine the short range order in these glasses by combining experimental data from state-of-the-art neutron and synchrotron facilities.
