University of Colorado Boulder - MOS analysis
At a silicon/SiO 2 interface the field in the oxide is about three times larger since the dielectric constant of the oxide (e ox = 3.9 e 0) is about one third that of silicon (e s = 11.9 e 0). The electric field in the semiconductor changes linearly due to the constant doping density and is zero at the edge of the depletion region, based on the full depletion approximation.
