| Outline of Final Research Achievements |
In this study, development of high performance organic phototransistor (OPT) utilizing surface plasmon resonance (SPR) was attempted. The intense electric field of SPR would enhance optical absorption of organic semiconductor film and sensitivity of OPT. Use of Long-range surface plasmon resonance (LRSPR) accompanying more intense electric field compared to normal SPR was mainly investigated. The LRSPR excitation in the device was confirmed through reflection property, and the prepared OPT exhibited large sensitivity for p-polarized light irradiation inducing LRSPR.
