Lead Iodide Perovskite Granular Nanowire Photodetectors with High Detectivity and Photoresponsivity |
| 초록 |
We demonstrate the first results showing the facile cost-effective two-step strategy for fabrication of CH3NH3PbI3 based perovskite granular nanowires (GNWs) and high-performance photodetectors. Our study has shown that the GNW photodetectors have high internal gain and responsivity at low bias with best reported Detectivity based on perovskite NWs to date. Furthermore, we present the successful patterned area attached perovskite GNW for 8 x 8 integrated photosensor arrays that were able to detect incident photonic signals with high resolution. The results clearly showed that GNWs are very promising materials for constructing high-performance photodetectors, and they warrant exploration for use in other photo electronic applications. |
