· Rb8 Se20

Rb8Se20 is a rubidium selenide compound belonging to the chalcogenide semiconductor family, composed of rubidium and selenium in a fixed stoichiometric ratio. This material is primarily of research and developmental interest rather than established industrial production, studied for its potential in solid-state ionics, photovoltaic applications, and thermal energy conversion due to the ionic mobility of rubidium and the semiconducting properties of the selenium lattice. Engineers considering this material should recognize it as an experimental compound—its adoption would depend on performance validation in specific device configurations where rubidium-ion conduction or selenium-based bandgap characteristics offer advantages over more conventional alternatives like halide perovskites or established selenide semiconductors.
