· Rb2NbCuSe4

Rb₂NbCuSe₄ is a quaternary chalcogenide semiconductor compound combining rubidium, niobium, copper, and selenium elements. This is a research-stage material studied for its potential in optoelectronic and thermoelectric applications, belonging to the broader family of multinary semiconductors that can exhibit tunable bandgaps and favorable charge transport properties. The material's structural complexity and composition make it of interest for exploring new semiconducting phases, though industrial adoption remains in early stages compared to conventional semiconductors.
