(In2O3)
In2O3 is a transparent n-type semiconductor with a cubic bixbyite crystal structure, widely used in optoelectronic and sensing applications. It exhibits high optical transparency in the visible range combined with good electrical conductivity, especially when doped (e.g., as indium tin oxide, ITO). These properties make it essential for transparent electrodes in displays, touchscreens, and solar cells. In2O3 also shows sensitivity to various gases, making it suitable for gas sensing devices. Its tunable electronic properties and compatibility with thin-film deposition techniques further enhance its role in advanced electronic and photonic technologies.
