· ScAlO3

ScAlO3 (scandium aluminum oxide) is a ceramic semiconductor compound combining scandium and aluminum oxides, offering potential as a wide-bandgap semiconductor material. This compound is primarily investigated in research and development contexts for high-temperature electronics, optical devices, and advanced integrated circuits where superior thermal stability and electrical properties are required compared to conventional semiconductors. ScAlO3 belongs to the family of rare-earth and transition-metal oxides that show promise for next-generation power electronics and RF (radio frequency) applications in demanding environments.
