Why semiconductors used as photocatalysis?
Semiconductors are used in photocatalysis due to their unique electronic properties, which enable them to absorb light and generate electron-hole pairs upon excitation. These charge carriers can then facilitate redox reactions, allowing for the degradation of pollutants or the conversion of CO2 into useful products. Their tunable bandgap energies allow for optimization of the photocatalytic activity under various light conditions. Additionally, semiconductors are often abundant and can be engineered to enhance stability and efficiency in photocatalytic applications.
Why semiconductor is called semiconductor not semiinsulator?
The purpose of semiconductors is to control the amount of conduction, not the amount of insulation.
Are semiconductors extremely hard?
Semiconductors are not considered extremely hard; in fact, they are relatively brittle materials. They can be fragile and may break or crack under mechanical stress. However, their hardness can vary depending on the specific semiconductor material, such as silicon or gallium arsenide. Overall, while they possess useful electrical properties, their physical hardness is not a defining characteristic.

Dielectric metals are also used in antennas, sensors, and other electronic components where a combination of electrical conductivity and insulation is needed.
Do semi conductors permit flow of electricity better than insulators?
Yes, semiconductors allow the flow of electricity better than insulators, but not as well as conductors. Semiconductors have conductivity values between those of conductors and insulators, making them useful for controlling the flow of electric current in electronic devices.
Element that has both properties of metals and nonmetals?
An element that exhibits properties of both metals and nonmetals is called a metalloid. Metalloids, such as silicon, arsenic, and germanium, have characteristics of both metals and nonmetals, making them useful in various applications, such as in semiconductors and electronic devices.
