Numerical modeling has been used to study the temperature dependence of the chemical potential and the occupation of the Landau subbands in a two-dimensional electron gas. Calculations were performed for various values of the filling factor ν, taking into account the level broadening due to scattering events. Graphs depicting the temperature dependence of the electron concentration within the Landau subbands were constructed. These dependencies enable the analysis of the thermal excitations of electrons between subbands. Additionally, a simple model was used to identify the thermal excitations of electrons within a single subband.
