Integer quantum Hall effect thumb|360x360px|Animated graph showing filling of Landau levels as B changes and the corresponding position on a graph of hall coefficient and magnetic field|Illustrative only. The levels spread out with increasing field. Between the levels the quantum hall effect is seen. DOS is the density of states.
