Figure 2.
(a) Experimental transfer characteristics of a PSeDPPDTT-based FET (L = 20 μm, W = 1000 μm) as a function of temperature. Solid lines are fits to Equation (1). (b) Replotted transfer characteristics of (a) on a double logarithmic scale. Solid lines are fits to extract the parameter γ for each temperature. (c) Extracted values of γ from (b) plotted versus 1/T. The extrapolated dashed linear fit yields the intersection with the vertical axis while the value of T0 is derived from the slope.
