What is the typical band gap of tin oxide sno_2 2?
The fundamental band gap of SnO2 was found to be 3.67 eV. This is very similar to the experimentally observed fundamental band gap of 3.59 eV.
Is FTO n-type or p type?
So, FTO and ITO in this work are n-type semiconductors.
Is SnO2 a semiconductor?
Tin oxide (SnO2) is one such very important n-type oxide and wide band gap (3.6 eV) semiconductor. Its good quality electrical, optical, and electrochemical properties are exploited in solar cells, as catalytic support materials, as solid-state chemical sensors and as high-capacity lithium-storage.

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.
What is FTO substrate?
FTO (Fluorine-doped Tin Oxide) glass is a transparent conductive metal oxide that can be used in the fabrication of transparent electrodes for thin film photovoltaics, such as: organic photovoltaic, amorphous silicon, cadmium telluride, dye-sensitised solar cells, and hybrid perovskites.
What is tin oxide used for?
Tin oxide, in which tin is in the +4 oxidation state, is useful in making ceramic bodies opaque, as a mild abrasive, and as a weighting agent for fabrics.
What is the energy gap in Si semiconductor?
1.17
Semiconductor Band Gaps
| Material | Energy gap (eV) | |
|---|---|---|
| Si | 1.17 | 1.11 |
| Ge | 0.74 | 0.66 |
| InSb | 0.23 | 0.17 |

How is energy band gap calculated?
(hv) can be calculated form wavelength using: (hv = 1240/wavelength);Extrapolating the straight line portion of the curves to zero absorption coefficient value gives the energy band gap value.
