| Abstract(in English) | The detailed operation mechanism of organic field effect transistors (OFETs) has not been clarified yet though they have been widely studied. We have investigated influence of source and drain electrodes on rubrene single crystal OFETs. In the case of using a silver (Ag) paste, the saturated drain current is proportional to the gate voltage squared and in the case of evaporated either gold (Au) or Ag, that is proportional to the gate voltage cubed. The drain current was mainly controlled by carrier injection from the electrode when Au or Ag was used. The transfer characteristic of OFET using a Au/Ag (20nm) electrode was close to that of OFET using a Ag paste. This indicates that Ag particles decrease the potential barrier height of carrier injection by enhancement of electric field. |
