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). |
