Original Abstract

The source-drain current-voltage characteristic is linear and symmetric at low voltages. The linearity and symmetry can be influenced by the electric potential of a gate electrode. Because the process is sensitive to the type of semiconductor, the method – “modified field effect transistor method” – can be used for the determination of the type of majority charge carriers. No insulating layer between the source-drain and gate electrodes is used. The effect is demonstrated on P- and N type organic semiconductors, 6-bis[5-(benzofuran-2-yl)-thiofen-2-yl]-2,5-bis(2-ethylhexyl) pyrrolo[3,4-c]pyrrole-1,4-dione [DPP(TBFu)2] and phenyl-C61-butyric acid methyl ester [PCBM], respectively.
