The influence of the level broadening on the chemical potential and the heat capacity of two-dimensional electron system

<div>Experiments on two dimensional electron systems (2DES) in a magnetic field show a broadening of an otherwise delta-like density of states. This broadening has been attributed as an effect of impurity scattering, electron-electron interactions, electron transfers into a reservoir of electronic states, or disorder, among others. As this broadening is usually present in 2DES, this work incorporates the Landau level broadening to have a more realistic electron system. Its effect on the chemical potential and the heat capacity is simulated.
