Fig. 3

a Rectification ratio of the GPETNC in different cation-chloride solutions with concentrations of 0.1 M. b I–V curves of the GPETNC in KCl solutions with different concentrations. Error bars were the standard deviations from the average of three independent records. c Rectification ratio of the GPETNC in KCl solutions with different concentrations.
