Fabrication of Ion Gel-Gated Organic Field Effect Transistor for UV detection Using Photochromic Molecules |
| 초록 |
Recently, several groups have demonstrated that ion-gel based on a mixture of an ionic liquid and a polymer can be used as gate dielectrics to obtain high capacitance and charge mobility in OFET devices. It is important to obtain high value of photocurrent with low gate voltage for UV sensor application. In this study, we presented a UV sensitive OFET device with photochromic molecule and ion-gel film as the dielectric layer for the UV photosensor application. We fabricated the ion gel film based OFET devices (top-gate, top-contact type) by simple method. The devices showed reversible photo-response upon alternating irradiation with UV and visible light. Also, the device showed an high photoresponsivity under UV light. |
