· JVASP-24769· RbAsSe2

RbAsSe₂ is a ternary chalcogenide ceramic compound combining rubidium, arsenic, and selenium in a layered crystal structure. This material belongs to the family of chalcogenide semiconductors and is primarily of research interest rather than established in high-volume industrial production. The compound is investigated for potential applications in infrared optics, nonlinear optical devices, and solid-state photonics where its unique combination of optical transparency in the infrared spectrum and semiconductor properties may offer advantages over traditional alternatives like zinc selenide or gallium arsenide.
