Overview

About TeSe

TeSe is a binary chalcogenide compound that exists as a thermodynamically stable phase on the convex hull. As a semiconducting material, it represents a significant intersection of tellurium and selenium chemistry, offering a tunable electronic environment that is highly relevant for fundamental materials research.

Given its extensive documentation across multiple databases, this compound serves as a critical reference point for understanding the structural diversity of chalcogen-based systems. Its stability and semiconducting nature make it a compelling subject for studies involving phase-change materials and optoelectronic device architectures.
