examples of n-type semi-conductors
Answers
Explanation:
The pentavalent elements have five electrons in the valence shell. Theexamples of pentavalent impurities are Phosphorus (P), Arsenic (As), Antimony (Sb).
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.
