{{#category_index:H|hole}}
- A mobile vacancy in the electronic valence structure of a semiconductor (an atom with less than its normal number of electrons). P-type semiconductors have an excess of holes. An electron from a neighboring atom can fill the hole so that in effect the hole moves to the neighboring atom. The apparent movement of holes in an electric field is equivalent to an electric current.
- A borehole.
