Question

What is p-type and n-type semiconductor?

Answer 1

p-type semiconductors:

1. p-type semiconductors carry holes in the majority.
2. It is a positive type semiconductor and it means it needs $1$electron.
3. In p-type semiconductors minority charge carries electrons.
4. Below the figure is shown of p-type semiconductors:

n-type semiconductors:

1. It is a negative type semiconductor and it has an excess of $1$ electron.
2. In this semiconductor, the V group adds pentavalent impurity to the pure semiconductor.
3. Some examples of these impurities are Arsenic, Bismuth, etc.
4. N-type semiconductor is shown below:
