Made of material, usually a semiconductor such as silicon, that has been doped with impurities so that it has an excess of electron holes.

[p(ositive)-type, from the behavior of electron holes as carriers of positive charge.]


1. (Electronics) (of a semiconductor) having a density of mobile holes in excess of that of conduction electrons
2. (Electronics) associated with or resulting from the movement of holes in a semiconductor: p-type conductivity. Compare n-type
