Spatial variation of the valence band and conduction band edges associated with a varying electric potential. Near a semiconductor boundary it can deplete mobile charge carriers or create a semiconductor inversion layer.
Band bending is a phenomenon that occurs in semiconductor physics and materials science, particularly at the interface between two different materials, such as a semiconductor and a metal or between two different semiconductors. It describes the change in energy band structure, specifically the bending of the energy bands (valence band and conduction band) in response to an electric field, charge distribution, or the presence of interfaces.
