(A) The dimensionless amplitude factor 27 plotted as a function of temperature $T$ measured in the units of $\hslash {\omega }_c$ for three different values of $l$. (B) The sum of two edge currents $J_{\text{tot}}$ in $\mu A$ as a function the Landau filling factor $\nu$ that is introduced for the cases of 2DEG and graphene in main text. The Fermi energy is assumed to be $E_F=500\hspace{0.17em}\text{K}$ and the level broadening $\mathrm{\Gamma }=0.5\hspace{0.17em}\text{K}$. The cyclotron energy $\hslash {\omega }_c=E_f/\nu$. Note that $T_1>T_2$ for the blue curves and $T_1<T_2$ for the red ones. The direction of the temperature gradient strongly affects the shape of the oscillations.
