Fig.\[figure:bands\]e). These are reminiscent of a similar behavior in liquid-gated FL graphene, where their appearance was linked to the opening of interband scattering channels upon the crossing of high-energy sub-bands[@YePNAS2011; @Gonnelli2dMater2017; @PiattiAppSS2017]. Even in the absence of energy-dependent scattering, Ref. showed that $\sigma_{2d}$ can be expressed as: $$\sigma_{2d}=e^{2}\tau\langle v_{\parallel}^{2}\rangle N\left(E_{F}\right)\propto e^{2}\langle v_{\parallel}^{2}\rangle\label{eq:sigma_velocity}$$ where $\tau\propto N(E_F)^{-1}$ is the average scattering time, and $N\left(E_{F}\right)$ is the density of states (DOS) at $E_F$. This implies that $\sigma_{2d}$ is proportional to the average of the squared in-plane velocity $\text{\ensuremath{\langle}}\ensuremath{v_{\parallel}^{2}}\text{\ensuremath{\rangle}}$ over the FS[@BrummePRB2016]. Since $\text{\ensuremath{\langle}}\ensuremath{v_{\parallel}^{2}}\text{\ensuremath{\rangle}}$ linearly increases with $n_{2d}$ and drops sharply as soon as a new band starts to get doped[@BrummePRB2016], the kinks in $\sigma_{2d}$ (or, equivalently, $R_s$) at $T\lesssim15$K can be used to determine the onset of doping of the sub-bands in the Q/Q’ valleys. At T=0, the kink is a sharp drop in $\sigma_{2d}$, emerging for the doping value at which $E_F$ crosses the bottom of the next sub-band. This correspondence is lost due to thermal broadening for T$>$0, leading to a smoother variation in $\sigma_{2d}$. If T is sufficiently large the broadening smears out any signature of the kinks, Fig.\[figure:transport\]. Ref. calculated that, at finite T, the conductivity kinks define a
