Question

Distinguish between n-type and p-type semiconductors

Answer 1

Definition of Semiconductor:

Semiconductors are materials that have conductivity lesser than the conductivity of conductors and more than the conductivity of non-conductors or insulators. Semiconductors can be compounds such as gallium arsenide or pure elements, such as germanium or silicon.

Difference between n-type and p-type semiconductors:

n-type semiconductor	p-type semiconductor
1. Its conductivity is mainly due to electrons.	1. Its conductivity is mainly due to holes.
2. It is completely neutral.	2. It is entirely neutral.
3. $I=I_e$ and $n_e>>n_h$	3. $I=I_h$ and $n_h>>n_e$
4. The majority are electrons and the minority are holes in n-type semiconductors	4. The Majority are holes and Minorityare electrons in the p-type semiconductors

The diagram is given below shows both an and p-type conductor
