Abstract

The phase equilibria in the system SbTeI-BiTeI were studied and the T-x phase diagram of the system was constructed using DTA and XRD methods. It was established that, the system is stable in subsolidus area and forms substitutional solid solutions based on the initial compounds. There are ~67 mol% and ~10 mol% solubility regions on the basis of BiTeI and SbTeI compounds, accordingly. New solid solutions obtained based on the BiTeI compound are of interest as topological insulator materials and Rashba semiconductors.
