ITO is a mixed oxide of [[indium]] and [[tin]] with a melting point in the range 1526–1926&nbsp;°C (1800–2200 [[Kelvin|K]], 2800–3500&nbsp;°F), depending on composition. The most commonly used material is an oxide of a composition of ca. In<sub>4</sub>Sn. The material is a [[n-type semiconductor]] with a large [[bandgap]] of around 4 eV. ITO is both transparent to visible light and relatively conductive. It has a low electrical [[resistivity]] of ~10<sup>−4</sup> [[Ohm|Ω]]·cm, and a thin film can have an optical transmittance of greater than 80%.<ref name="Chen-2013">{{cite journal|doi=10.1021/la4033282 | pmid=24117323 | volume=29 | issue=45 | title=Fabrication of Highly Transparent and Conductive Indium–Tin Oxide Thin Films with a High Figure of Merit via Solution Processing | journal=Langmuir | pages=13836–13842 | last1 = Chen | first1 = Zhangxian| year=2013 }}</ref> These properties are utilized to great advantage in [[touch-screen]] applications such as [[mobile phone]]s.
