Is ITO a semiconductor?

What is ITO electrode?

This quite unique material transmits only visible light whereas it does not transmit UV radiation. Our ITO electrodes consist of 100 nm thick of ITO layer deposited on quartz or borosilicate glass substrate (0.5 mm thick).

Is ITO a dielectric?

In this work, the ITO was used as a dielectric layer rather than a conductive material, which had been discussed and modeled in [15]. Over the last few decades, high-κ dielectric metal oxide thin film-coated optical sensors have been a high-interest topic.

Is ITO an insulator?

ITO is a heavily doped semiconductor. Essentially it is In2O3, containing a high density of tin donors (10^20 to 10^21cm-3). Undoped In2O3 is an insulator with a direct optical gap of about 3.5 to 3.7eV. … The conductivity of the ITO is due to the electrons donated to the conduction band.

Is ITO a metal?

In the infrared region of the spectrum it acts as a metal-like mirror. Indium tin oxide is one of the most widely used transparent conducting oxides because of its electrical conductivity and optical transparency, the ease with which it can be deposited as a thin film, and its chemical resistance to moisture.

Is indium tin oxide a semiconductor?

Indium tin oxide (ITO) is a well-known n-type degenerate semiconductor with a wide variety of electronic and optoelectronic applications.

Is ITO conductive?

The ITO films are highly transparent (90.2%) and conductive (ρ = 7.2 × 10–4 Ω·cm) with the highest figure of merit (1.19 × 10–2 Ω–1) among all the solution-processed ITO films reported to date.

Is Indium Tin Oxide a semiconductor?

Indium tin oxide (ITO) is a well-known n-type degenerate semiconductor with a wide variety of electronic and optoelectronic applications.

Why is ITO type N?

ITO film is basically n-type degenerate semiconductor, for which a simple efficient solar cell is obtained when rectifying contact is formed between ITO and Si.
