Electron transport properties above Tc. The red and blue dots represent the temperature dependences of sheet resistance R□ for sample S1 and S2, respectively, while the yellow and green lines are the results of fitting analysis using Equations 1 to 3. ΔR□ is defined as the decrease in R□ between 20 and 5 K. The inset shows Tc as a function of Rn,res, revealing no clear correlation between them.
