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.;
