Gold Nanostar-Perovskite Hybrid System for Flexible High-Performance Graphene Photosensors |
| 초록 |
Hybrid materials in photodetectors(PDs) can give synergistic effect, enhancing each optoelectronic properties. Here, we describe hybrid graphene PDs introducing of strong light trapping, and hot electron transfer effects of gold nanostars (GNSs) and efficient charge carrier transfer of perovskite light absorption material. Hybrid GNSs and perovskite decorated perovskite-based graphene PDs exhibit considerably enhanced photo-responsive properties with a photo responsivity of 5.90 × 104 A W−1 and specific detectivity of 1.31 × 1013 Jones, which are comparable to commercialized inorganic material based devices. Furthermore, the flexible 10 × 10 PD array shows excellent physical stabilities and a well-resolved mapped image of optical signal. |
