  We have used the classical Hall effect to electrically characterize Indium
Tin Oxide (ITO) films grown by two different techniques on silica substrates.
ITO films have the unique property that they can be both electrically
conducting (and to be used for a gate electrode for example) as well as
optically transparent (at least in the visible part of the spectrum). In the
near infrared (NIR) the transmission typically reduces. However, the light
absorption can in principle be compensated by growing thinner films.
