· JVASP-155383· Cu2HgTeSe4

Cu2HgTeSe4 is a quaternary chalcogenide compound belonging to the metal chalcogenide family, combining copper, mercury, tellurium, and selenium in a crystalline structure. This material is primarily of research and development interest rather than established industrial production, investigated for potential applications in thermoelectric energy conversion and semiconductor devices where its mixed-metal composition offers tunable electronic properties. The compound exemplifies experimental work in quaternary semiconductors aimed at improving efficiency in waste heat recovery and solid-state electronic applications compared to simpler binary or ternary alternatives.
