[10a-Z25-1] Probing the electric-field behavior in DPh-BTBT OFETs by Sum-Frequency Generation imaging spectroscopy
Keywords:organic field effect transistor, sum frequency generation spectroscopy
By applying a voltage to the gate electrode, increase in the SFG signal derived from the insulating monolayer at the edge of the source and drain electrodes was observed. This phenomena is due to a strong electric field is generated around the edge of the gold electrode when a gate voltage is applied, and it reaches the gate insulating layer.
