· JVASP-104770· YSe2

YSe₂ is a layered ceramic compound composed of yttrium and selenium, belonging to the transition metal dichalcogenide family. This material is primarily of research interest rather than established in commercial production, with potential applications in semiconductor and optoelectronic devices due to its layered crystal structure similar to other 2D materials. Engineers may explore YSe₂ for emerging applications in electronics and photonics where its electronic band structure and anisotropic properties could offer advantages over traditional semiconductors, though material availability and processing methods remain active areas of investigation.
