| Abstract: | The Hall conductivity of a two-dimensional system of free, independent electrons is calculated using linear response theory. Emphasis is on the influence of the edge states introduced by a confining potential. It is shown that within the Kubo formalism the quantized values of the Hall conductivity may be described by bulk states as well as by edge states only. The influence of a random potential is discussed. |
