Аннотация:
We report first thermodynamic measurements of the temperature derivative of
chemical potential ($\partial \mu/\partial T$) in two-dimensional (2D) electron
systems. In order to test the technique we have chosen Schottky gated
GaAs/AlGaAs heterojunctions and detected experimentally in this 2D system
quantum magnetooscillations of $\partial \mu/\partial T$. We also present a
Lifshits–Kosevitch type theory for the $\partial \mu/\partial T$
magnetooscillations in 2D systems and compare the theory with experimental data.
The magnetic field dependence of the $\partial \mu/\partial T$ value appears to
be sensitive to the density of states shape of Landau levels. The data in low
magnetic field domain demonstrate brilliant agreement with theory for
non-interacting Fermi gas with Lorentzian Landau level shape.
