What is an N-type semiconductor?
Q: What is an N-type semiconductor?
A: An N-type semiconductor is a type of material used in electronics that is made by adding an impurity to a pure semiconductor such as silicon or germanium.
Q: What impurities are used to make an N-type semiconductor?
A: The impurities used to make an N-type semiconductor may be phosphorus, arsenic, antimony, bismuth or some other chemical element.
Q: Why are they called donor impurities?
A: They are called donor impurities because they give a free electron to a semiconductor.
Q: What is the purpose of adding donor impurities to a pure semiconductor?
A: The purpose of adding donor impurities is to make more charge carriers or electron wires available in the material for conduction.
Q: How does adding donor impurities affect the conductivity of a semiconductor?
A: Adding donor impurities makes the final material a lot more conductive than the original silicon or germanium.
Q: Can other elements besides phosphorus, arsenic, antimony, and bismuth be used as donor impurities?
A: Yes, other chemical elements can be used as donor impurities.
Q: Why are more charge carriers important in a semiconductor?
A: More charge carriers are important in a semiconductor because they carry electrical current and enable the semiconductor to conduct electricity.
