Molecular formula :

nature : semiconductor valence band of electronic caused by the heat or optical excitation of the conduction band, or by the main type impurity capture the valence band left an empty-level (that is the price of lost electronic keys), referred to as the hole. When it is near the valence electron atoms occupy, in the vicinity will create a new hole, the effect is equivalent to the mobile hole. People always regarded as a hole in the valence band free exercise, Positive entities, easy and precise.
