· JVASP-75500· TaAsSe

TaAsSe is a ternary ceramic compound combining tantalum, arsenic, and selenium, belonging to the family of chalcogenide ceramics with potential semiconducting or optoelectronic properties. This material is primarily of research interest rather than established industrial production, studied for its electronic structure and potential applications in solid-state devices. Engineers would consider this compound in exploratory materials development for niche applications where the unique combination of these elements offers advantages in energy band structure or thermal properties unavailable in conventional alternatives.
