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.
What else can I help you with?
Why do we mostly use indirect semiconductors?
The indirect band gap semiconductors like silicon and germanium are mostly used because they are elemental, plentiful, and easier to process than the direct band gap semiconductors which are alloys or compounds.
Which type of element is used as semiconductors?
Commonly doped silicon is used to make semiconductors, but advancements in organic electronics now mean that semiconductors can be made from molecules made from elements such as carbon, hydrogen, oxygen, sulphur, nitrogen and a few others.
What is the purpose of semiconductors?
Semiconductors are the materials that has conductivity higher than the insulator but lower than the metals. Can be used in various purpose i.e., LED, LASER also fabricating various ICs etc.
What are examples of semiconductors?
Germenium and silicon are the examples of Semiconductors.

Is silicon and germanium used in electronics as semiconductors?
Yes
What are some uses for a semiconductor?
Semiconductors are usually found in electronic appliances, such as radios and computers. Semiconductors are electrically conductive and are used for power.
What three elements that are used in semiconductors?
Silicon is the most common element used in semiconductors due to its abundance and well-understood properties. Germanium is another element used in semiconductors, although less commonly than silicon. Arsenic and phosphorus are often incorporated as dopants to introduce either additional electrons (n-type doping) or electron vacancies (p-type doping) in semiconductors.
Why the compound semiconductors are not suitable for making transistors and ICs?
Compound semiconductors have very low lifetime of charge carriers and hence they are not used for making Transistors and ICs.Rather it is used for making LEDs and LASER diodes.So the compound semiconductors are called photo-diodes. -M.R
Substance in between conductors and insulators used in transistors?
