Question

Describe the properties of n-type and p-type semiconductors

Answer 1

doping produces n type and p type semiconductors

N type semiconductor

1. When pentavalent atom added to the intrinsic semiconductor produces n type semiconductor.

2. majority carriers are electrons

3. minority carriers are holes.

4. fermi level near the condition band.

P type semiconductor

1. When trivalent atom added to the intrinsic semiconductor produces p type semiconductor.

2. majority carriers are holes

3. minority carriers are electrons

4. fermi level near the valance band.
