Memory Effect Induced by Charge Transfer of Field-Driven Photocarriers in Organic Transistor and Its Application |
| 초록 |
Understanding modulation of electrical performance in organic field-effect transistors (OFETs) under light irradiation is highly significant when the device’s target applications are photo sensors. In general, the light applied to OFETs is known to temporarily modulate the electrical properties (threshold voltage shift, current rise, etc.). In this study, we investigated a unique memory effects under light irradiation when an organic semiconductor dinaphtho[2,3-b:2’,3’f]thieno[3,2-b]thiophene (DNTT) and novel polymer insulators are used as a thin film in OFETs. The devices confirmed that the threshold voltage shifted rapidly due to the photo- and field-induced charge transfer effect when light illumination and gate-bias are applied at the same time. Furthermore, it was found that this finding highly depends on the wavelengths. Consequently, we demonstrated highly stable photo-sensitive memory OFETs, which allows the development of a memory device with a novel driving principle. |
