Abstract

We fabricated OTFT device using soluble π-conjugated dendrimer, 4(HPBT)-benzene, and investigated photoinduced characteristics of the device. The OTFT device using 4(HPBT)-benzene as an active layer showed a carrier mobility as high as 6×10-3 cm2/Vs in dark conditions and sensitive photoinduced characteristics even at low light intensity. We observed the shift of threshold voltage and saturation current in photoinduced field-effect transistor characteristic curves. Through the measurements of the photoinduced saturation current as a function of drain voltages, we estimated photoinduced charge density of the OTFT.
