Highly Sensitive Ultraviolet Light OFET Photodetector Based on Photoactive Organic Gate Dielectrics with an Azobenzene Derivative |
| 초록 |
Recently, many research groups have investigated 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 azobenzene derivative and ion-gel film as the gate dielectric layer for the UV photosensor application. We fabricated the ion gel film based OFET devices with top-gate and top-contact type structure by simple method. The devices showed reversible photo-responses upon alternating irradiation with UV and visible light and also had an high photoresponsivity under UV light. |
