Organic field-effect transistors source-drain current

Figure 7. (a) Measured current-voltage characteristics of organic field-effect transistors under ambient conditions and after exposure to vapors of various organic solvents, (b) Measured differential response of organic field-effect transistors after exposure to the same organic solvents. THF is tetrahydrofuran. Iqs/s the drain-source current, and Vos is the drain-source voltage. 

Fig. 12.13 An organic thin-film field-effect transistor, schematic. The current Id in a weakly semiconducting organic film (black) between two electrodes S (source) and D (drain) can be controlled by the gate (G) voltage Vc- The latter influences charge carriers capacitively in a thin layer of the...
