General description

Indium tin oxide (ITO) is widely used as transparent conducting oxides. Its major characteristics are electrical conductivity, optical transparency and the ease to be deposited as films.

Application

ITO cover slides may be used for closed digital microfluidic devices and as a transparent electrodes in display and other optoelectronic devices. Some other potential uses that have been reported are:
  • Eumelanin samples prepared on ITO covered glass substrates.
  • Interface windows of the liquid cell for optical beam deflection (OBD) sensing contain a 20-nm-thick indium tin oxide film.
  • Mesoporous TiO2 films were formed on ITO conductive glass substrates.

Physical properties

Thickness of ITO coating is 150-300 Å.
Resistance may increase to as high as 375 Ω when exposed to temperatures of 300 °C for 30 minutes or more.

To avoid damaging the thin film coating when determining which side is coated, lightly touch the barrelsof the probes to the same surface of a single-side coated product. Testing the alternate side will quicklyshow one with a low resistance as compared to the opposing side, which will exhibit an essentially infiniteresistance.
