Logarithm of ρxx( B )(ν = 3) versus the inverse of temperature 1/ T . The logarithm of ρxx(B)(ν = 3) versus the inverse of temperature 1/T at different gate voltages (and hence B) for sample C. From left to right: B = 5.72 (pentagon), 5.46 (star), 5.21 (hexagon), 4.97 (diamond), 4.70 (inverted triangle), 4.55 (triangle), 4.39 (heptagon) and 4.25 (square) T, respectively. The slopes of the straight line fits Δs are shown in Figure 7.
