| Abstract(in English) | Electric field E, mobility μ and carrier density en are key parameters used to discuss the operation mechanism of Organic Field transistors (OFETs). OFETs are mainly ruled by carriers injected from the source electrode. Hence space charge field is formed in OFETs. It is a significant issue to evaluate electric field distribution along the FET channel. In our previous studies, we proposed a novel technique for evaluating the electric field distribution in OFETs using the second harmonic generation (SHG) activated by the d.c. electric field induced polarization of organic semiconductor. In this work, in-plane anisotropy of electric field in pentacene FET was investigated with polarized SH light. Consequently, d.c. electric field along the channel is shown to be determined for pentacene films with crystalline domain size of about 1μm. |
