Two-dimensional electron systems

The study of two-dimensional electron systems (2DES) is essential to understanding the quantum Hall effect. SanD numerically and analytically investigates the behavior of the temperature- and magnetic field-dependent energy fluctuations in the 2DES spectra and its corresponding density of states. It is found that Landau level broadening due to disorder in a 2DES causes variations in its interlevel and intralevel excitations. At a characteristic low temperature, this broadening parameter has no effect on the specific heat of the system.
