· JVASP-14991· YSe

YSe is a ceramic compound composed of yttrium and selenium, belonging to the family of rare-earth chalcogenides. This material is primarily of research interest rather than a widely established commercial ceramic, being investigated for potential applications in optoelectronics and solid-state physics where its electronic and thermal properties may offer advantages in specialized environments. Engineers would consider YSe in advanced materials development contexts where conventional ceramics or semiconductors are inadequate, particularly in systems requiring rare-earth doping or tunable electronic behavior.
