Resistivity and metallic behavior. (a) Zero-field resistivity as a function of T ranging from T = 4.8 K to T = 78 K. The red solid line corresponds to a fit to Eq. (1). The best fit is limited at T > 30 K, as shown in the inset. (b), (c) ρxx (B = 0) as functions of T2 and T3, respectively. The red dashed lines are a guide to the eye.
