The presence of this phenomenon in a semiconductor causes band-bending.
The presence of this phenomenon in a semiconductor causes band-bending. The divergence of this quantity is the charge density over permittivity according to Gauss' Law, and Maxwell added the displacement current term to Ampere's Law to describe how a magnetic field is produced by a time-varying one of these. It is always zero inside a conducting sphere by the shell theorem, and it is inversely proportional to the square of distance for charged particles. For 10 points, name this vector field defined as force per unit charge.
