Question

3) Explain n-type semiconductors.​

Answer 1

Answer:

An N-type semiconductor is a type of material used in electronics.

It is made by adding an impurity to a pure semiconductor such as silicon or germanium. The impurities used may be phosphorus, arsenic, antimony, bismuth or some other chemical element. They are called donor impurities. The impurity is called a donor because it gives a free electron to a semiconductor. The purpose of doing this is to make more charge carriers, or electron wires available in the material for conduction. The final material is a lot more conductive than the original silicon or germanium.
