· Cu4 As2 Sr1

Cu₄As₂Sr is a ternary intermetallic compound containing copper, arsenic, and strontium, classified as a semiconductor material. This is a research-phase compound that belongs to the family of complex metal arsenides; such materials are primarily investigated for their electronic band structure and potential thermoelectric or photovoltaic applications rather than for established industrial use. The arsenic-containing intermetallic system may offer interesting properties in niche electronic or energy conversion contexts, but practical applications remain largely unexplored compared to more conventional semiconductor alternatives.
