Renormalized mobility μ′ as a function of T for Vg = −0.125 (a), −0.145 (b), and−0.165 (c) V. The red and blue symbols denote the results obtained from the fits according to Equations 3 and 4, respectively. The insets are the zoom-ins of low-T results. The dotted lines represent the linear extrapolation of straight lines at T > 4 K.
