H2 Se1

H₂Se (hydrogen selenide) is a binary hydride semiconductor compound consisting of selenium and hydrogen, typically studied in the context of group VI hydride semiconductors and selenide-based materials. While not a primary commercial structural material, H₂Se is of research interest for thin-film deposition, quantum well heterostructures, and as a precursor in metal-organic chemical vapor deposition (MOCVD) for selenide optoelectronic devices. It represents an alternative within the hydride semiconductor family, offering different bandgap and transport properties compared to more common sulfides or tellurides, though practical engineering applications remain largely in the research and specialized semiconductor fabrication domains.
