Dimensionality-Tailored Quasi-2D Perovskites for Highly Stable and Efficient Photodetectors |
| 초록 |
In this work, we developed perovskite photodetector devices by integrating dimension-reduced (quasi-2D) perovskites instead of conventional three-dimensional counterparts. A series of quasi-2D perovskite films were synthesized to obtain advanced photodectors with improved stability while retaining the comparable electrical performance of conventional three-dimensional perovskites. The quasi-2D perovskite photodetector exhibited a responsivity of 0.53 A/W and detectivity of 2.20ⅹ1012 J, which is attributed to decreased leakage current. In addition, the current density of quasi-2D perovskite photodetector maintained 76 % while three-dimensional perovskite photodetector remained only 15 % of initial level after 2,000 hours. We confirm the stability of perovskite films via X-ray diffraction (XRD) and atomic force microscope (AFM) measurement. |
