Question

examples of n-type semi-conductors​

Answer 1

Explanation:

The pentavalent elements have five electrons in the valence shell. Theexamples of pentavalent impurities are Phosphorus (P), Arsenic (As), Antimony (Sb).

Answer 2

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.
