Energy levels localized in the
surface region of semiconductors, which do not bear any direct relation to the bulk energy distribution,
but which can exchange electrons with the bulk. In such a case a
space charge may
arise even when
(the free
charge density) is zero, i.e.
,
where
is the space
charge density and
is the
charge density associated with the surface states.
