Topological characterization of the Ge-Sb-Te phase diagram

Inorganic Materials Aims and scope

Abstract

Topological images of the Ge-Sb-Te phase diagram are constructed on the basis of two versions of the phase relations between the low-temperature forms of Ge1-δTe in the Ge-Te system. The images have the form of flow diagrams and graphs, with labeled nodes representing the phases existing in the system. The graph edges represent two-phase mixtures and are labeled by the numbers of the phase reactions in which these mixtures appear and disappear. The graphs help to visualize the topology of the phase diagram in a compact form and are convenient for topological characterization and identification of phase reactions at invariant points.
