Position of holes in p-type semiconductors

  1. Aug 11, 2013 #1
    where are the holes in the p-type semiconductor situated? in the conduction band or the valence band? i am talking about the holes formed because of the acceptor impurities, not the thermally generated ones.

    The valence band. In an acceptor type doped crystal, The number of electrons in the conduction band is less than the number of holes in the valence band (which has to be equal unless doped).

    In p-type semiconductors, electrons move from valence band to acceptor levels and hence empty states (holes) remain in the valence band.
