These samples show prominent signatures associated with the van Hove singularities (VHSs) and superlattice-induced mini-gaps (SMGs). Temperature-dependent field effect measurement shows that the difference between temperature-dependent resistivity and residual resistivity, $\\rho_{xx}(n,T) - \\rho_{0}(n)$, follows $~T^\\beta$ for $n$ between the main Dirac point (DP) and SMG.
