摘要：

The velocity of carrier motion in pentacene field effect transistor (FET) was evaluated by the time-resolved microscopic second harmonic generation (SHG) measurement. Under the pulse operation of organic FET (OFET), time evolution of the electric field distribution along the channel is observed by changing the delay time between laser pulses and voltage pulses that drive OFET. The peak position of SHG profile moves along OFET channel from source to drain electrode with increase in delay time reflecting carrier motion. The time-resolved SHG technique enables us to evaluate carrier velocity by tracing motion of the SHG peak. (C) 2008 American Institute of Physics.
