Abstract

The atomic structure of Te-rich amorphous germanium tellurides has been investigated experimentally with high-energy synchrotron radiation and modeled by means of the reverse Monte Carlo technique. Total and partial structure factors and pair correlation functions were simulated. It is shown that the structure of Ge₂₀Te₈₀ and Ge₁₅Te₈₅ glasses can be described by GeTe₄ tetrahedra as structural units which are bridged by Te-Te bonds.
