High Performance Photoimaging device using Multiple-Patterned Plasmonic Nanostructures |
| 초록 |
Insect eyes are composed of units called ommatidia which contains unique hierarchical structured cornea leading to efficient light absorption. Inspired by insect ommatidia, we fabricated photoimaging device consisting of organic photodiodes (OPDs) and organic resistive switching device (ORS). Multiple patterned plasmonic electrode was applied to OPDs, which lead to increased light absorption compared to flat electrodes. The responsivities of OPDs were greatly enhanced and the threshold voltages of the photoimaging device were reduced over half compared to flat electrode. The reproducibility of the device was also confirmed by bending test and multicycle usage test. Moreover, strong surface plasmon coupling of these nanostructured electrodes was observed by theoretical study and near-field scanning optical microscopy. From these results, it has been demonstrated that multiple patterned plasmonic nanostructures can be used as a highly effective optical design in optoelectronic devices. |
