Preferred Label : bending of energy bands;
IUPAC definition : The distribution of potential in the space charge region of a semiconductor results
in a change in the electron energy levels with distance from the interface. This is
usually described as 'bending of the energy bands'. Thus the bands are bent, upwards
if σ 0 and downwards if σ 0, where σ is the free charge density. When σ 0 the
condition of flat bands is met, provided no surface states are present.;
