Overview

About ReSTe

ReSTe is a complex ternary chalcogenide that exists as a thermodynamically stable phase on the convex hull. Its electronic character is defined as a near-zero-gap semimetal, placing it in a unique position between traditional metallic conductors and semiconducting materials.

This compound is of significant interest in materials science due to its structural stability and electronic behavior. It serves as a subject for fundamental research into the properties of rhenium-based chalcogenides, which are often explored for their potential in advanced electronic and optoelectronic device architectures.
