The standard composition consists of 90 wt.% indium oxide (In\u2082O\u2083) and 10 wt.% tin oxide (SnO\u2082), a ratio carefully optimized to achieve an excellent balance between electrical conductivity and optical transparency.<\/p><p>Rather than being a simple mixture, ITO is a precisely engineered ceramic material. Indium oxide is an n-type semiconductor with a wide band gap of approximately 3.6 eV, allowing high visible-light transmission while providing good electrical conductivity through free electrons. Tin oxide acts as a dopant that increases the carrier concentration in indium oxide, significantly reducing electrical resistivity without sacrificing transparency.<\/p><p>The combination of In\u2082O\u2083 and SnO\u2082 also stabilizes the material by reducing conductivity fluctuations caused by oxygen vacancies.
