| Abstract(in English) | The investigation and the control of the electrostatic interfacial phenomena is of specially importance to the field of organic electronic applications. Negative potential was formed across the pentacene films deposited on Al surface. As a result of the SHG spectrum of the pentacene/Al structure, distinct peak as observed at 620 nm, which is the main peak position of the absorption spectrum. This indicates that the electric dipolar SHG process was activated by the surface potential. In the bottom contact pentacene FET, decrease of the threshold voltage and the increase of the mobility was confirmed by the UV/ozone treatment of the surface of the source and drain electrode. As a result of the surface potential measurement, positive potential was observed for the pentacene films deposited on UV/ozone treated Au surface. The formation of the positive surface potential indicates that the accumulation of the holes around the electrode. This accumulation of the holes leads to the decrease of the threshold voltage. |
