摘要：

This work investigates the influence of low temperature, external magnetic field and broadened Landau levels on the thermodynamic properties of two-dimensional electron gas (2DEG) of InSb. The interplay between these two physical parameters on the magnetic field dependence of the chemical potential and the magnetization is calculated. In the absence of a complete theory that explains the Landau level broadening, experimental and theoretical studies in literature perform different model calculations of this parameter. Here it is presented that different broadening parameter of Gaussian-shaped Landau levels cause width variation in their contribution to interlevel and intralevel excitations. (C) 2013 Elsevier Ltd.
