· O14 Se4 Au4

O14Se4Au4 is an experimental intermetallic compound combining oxygen, selenium, and gold in a fixed stoichiometric ratio, classified as a semiconductor material. This composition falls within research into mixed-valence and multinary semiconductor systems, where gold typically acts as an electronic modifier in chalcogenide matrices. While not yet established in mainstream industrial production, materials in this chemical family are investigated for optoelectronic and thermoelectric applications where the unique electronic properties arising from gold-selenium interactions and oxygen incorporation could offer advantages over conventional semiconductors.
