Abstract: | The paper deals with the description of the measuring method of temperature modulated electric current and influence of electric field on current in organic electrochemical transistors (OECT). The results of temperature dependences of current-voltage characteristics and their interpretation are presented. The measurements were performed on the organic electrochemical transistors with 3 ionic liquids: a) 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imid (No1), b) 1-ethyl-3-methylimidazolium ethyl sulfate (No4) and c) 1-ethyl-3- methylimidazolium tetrafluoroborate (No9). The method enables to measure the voltage and temperature dependence of the current in one step. Thus, the measured current response is influenced not only by temperature change but also by relaxation processes at the same time. The result is the dependence of activation energy on the source-drain voltage. |
