Overview

About SrAs

SrAs is a binary inorganic compound composed of strontium and arsenic. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within its chemical system, supported by a significant body of structural data across multiple databases. Its electronic character is defined as near-zero-gap, placing it in the category of semimetallic materials. This electronic profile makes it a subject of interest for researchers investigating materials with unique charge carrier dynamics. While its specific applications are still emerging, its stability and electronic nature position it as a key candidate for fundamental studies in condensed matter physics.
