The resistance between opposite sides of a square.
Ito glass sheet resistance.
The ito glass is a thin transparent film similar to common glass but unlike glass it is a conductor of electricity because it is a kind of transparent conductive oxide tco.
Sheet resistance often called sheet resistivity is a measure of resistance of thin films that are nominally uniform in thickness.

Ito sheet resistance standards itosrs product description.
Ito coated glass substrates are widely used to organic inorganic heterojunction solar cells schottky solar cells cdte solar cells and other various thin film solar cells as transparent semiconductor oxide electrode materials since their transparency and high conductivity.
Indium tin oxide ito is a ternary composition of indium tin and oxygen in varying proportions.
It contains approximately 90 of tin oxide iv sno2 and 10 of indium oxide iii in2o3.
It is mostly used in research and development.
Ito glass is formed of tin oxide doped with indium.

The ito sheet resistance standard consists of a glass substrate with a thin film of indium tin oxide sputtered on it.
The ito sheet resistance standard consists of a glass substrate with a thin film of indium tin oxide sputtered on it.
It is commonly used to characterize materials made by semiconductor doping metal deposition resistive paste printing and glass coating examples of these processes are.
The ito thin films can be prepared by rf sputtering at a substrate temperature of 70 c on glass with 222 preferred orientation grain size of 7 nm high optical transparency of 95 in the wavelength range of 550 650 nm and sheet resistance of 103 ω higher than 36 ω of commercial ito.
Sheet resistance also known as surface resistance or surface resistivity is a common electrical property used to characterise thin films of conducting and semiconducting materials.
It is a measure of the lateral resistance through a thin square of material i e.
Depending on the oxygen content it can either be described as a ceramic or alloy indium tin oxide is typically encountered as an oxygen saturated composition with a formulation of 74 in 18 o 2 and 8 sn by weight oxygen saturated compositions are so typical that unsaturated compositions are.
