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.
