Nb4 Se18
semiconductor· Nb4 Se18
Nb4Se18 is a layered niobium selenide compound belonging to the transition metal chalcogenide family, synthesized primarily as a research material rather than a commercial product. This material is of interest in condensed matter physics and materials research due to its layered crystal structure, which can exhibit unique electronic and optical properties relevant to 2D materials science. Potential applications include novel semiconducting devices, thermoelectric materials, and optoelectronic components, though practical engineering deployment remains largely in the exploratory phase.
