· ScAgO2

ScAgO2 is a mixed-metal oxide semiconductor composed of scandium, silver, and oxygen, representing an emerging compound in the functional ceramics research space. While not yet established in mainstream industrial production, materials in this chemical family are investigated for applications requiring combined electrical conductivity and mechanical stability, particularly in contexts where silver's conductive properties and scandium's strengthening effects offer advantages over conventional semiconductors. Its development reflects ongoing research into high-performance oxide semiconductors for next-generation electronic and optoelectronic devices.
