Properties of P-type and N-type material & their differences

let us go through the properties of P-type and N-type semiconductors. Then we will compare P-type and N-type semiconductors, as well.

P-type and N-type material

In Figure 1, the left side material is a P-type semiconductor having negative acceptor ions and positively charged holes. The right side material is an N-type semiconductor having positive donor ions and free electrons.

Comparison of P-type and N-type materials

Comparison of P-type and N-type materials is given in table 1 below:

P-type Material N-type Material
The P-type semiconductor material is doped with acceptor impurity atoms.The N-type semiconductor material is doped with donor impurity atoms.
P-type material has a high hole concentration.N-type material has a high free electrons concentration
The concentration of free electrons in p-type material is very low.The concentration of holes in N-type material is very low.
P-type material contains negatively charged acceptor ions (immobile) and positively charged holes (free). N-type material contains positively charged donor ions (immobile) and negatively charged electrons (free).
