  P-type Dopants
The other type of dopants, the p-types, can be found in group 13 of the periodic table. The element boron (B) is one example of such a p-type dopant. These p-type dopants introduce something called holes in the semiconductor. You could say that they steal electrons from the semicondutor. Because of these electron deficiencies, the total negative charge is reduced and the holes can be thought of as positive charges, thus the name.
