· AuSe

AuSe is an intermetallic compound combining gold and selenium, representing a class of materials being investigated for semiconductor and optoelectronic applications. This compound is primarily of research interest rather than established industrial production, with potential applications in thermoelectric devices, photodetectors, and thin-film electronics where the unique electronic properties of gold-selenium interactions could be leveraged. Engineers considering AuSe would typically be working in advanced materials development or emerging device fabrication rather than conventional manufacturing, as the material remains largely in the experimental phase with limited commercial availability.
