· ScGaO3

ScGaO3 is a ternary oxide semiconductor compound combining scandium, gallium, and oxygen, belonging to the family of wide-bandgap oxides. This material is primarily investigated in research settings for optoelectronic and high-temperature semiconductor applications, where its structural stability and electronic properties offer potential advantages over conventional semiconductors in extreme environments. As a relatively early-stage compound, ScGaO3 represents part of the broader exploration into mixed-cation oxide semiconductors for next-generation power electronics, UV photonics, and high-temperature integrated circuits.
