· VCu3Te4

VCu3Te4 is an intermetallic compound combining vanadium, copper, and tellurium, belonging to the family of ternary metal chalcogenides. This is primarily a research material studied for its electronic and structural properties rather than an established commercial alloy. Interest in this compound stems from its potential in thermoelectric applications and semiconductor research, where copper tellurides and vanadium-containing intermetallics show promise for energy conversion and solid-state device performance.
