Cu1 As1 Se2
semiconductor· Cu1 As1 Se2
CuAsS₂ is a ternary chalcogenide semiconductor compound combining copper, arsenic, and selenium in a crystalline structure. This material belongs to the I-V-VI₂ chalcogenide family and is primarily of research and development interest rather than established commercial production. The compound is investigated for potential applications in photovoltaic devices, infrared optics, and solid-state electronic components, where its bandgap and optical properties may offer advantages in niche photonic and sensing applications compared to more conventional binary semiconductors.
