semiconductor

· ScTlO3

ScTlO3 is an experimental oxide semiconductor compound containing scandium and thallium. This material belongs to the perovskite or perovskite-related oxide family and is primarily of research interest rather than established industrial use. Potential applications span optoelectronics, photovoltaics, and high-temperature electronics, where the combination of scandium and thallium oxides may offer tunable bandgap or enhanced ionic conductivity compared to conventional oxides, though practical deployment remains limited pending further development of synthesis methods and performance validation.
