Perovskite and Conjugated Polymer Wrapped Semiconducting Carbon Nanotube Hybrid Films for High Performance Transistors and Phototransistors |
| 초록 |
This work proposes a universal approach to significantly improve mobility and operational stability with reduced dual-sweep hysteresis for perovskite based thin film transistors (TFTs) by coupling low dimensional lead-free perovskite material (C6H5C2H4NH3)2SnI4 (hereafter abbreviated as (PEA)2SnI4) with embedded conjugated polymer wrapped semiconducting carbon nanotubes (semi-CNTs). In (PEA)2SnI4/semi-CNT hybrid TFTs, semi-CNTs can provide highway-like transport paths, enabling smoother carrier transport with less trapping and scattering.3 We also demonstrate the performance of (PEA)2SnI4/semi-CNT hybrid phototransistors with ultrahigh photoresponsivity (R) of 6.3×104 A/W, and detectivity (D*) of 1.12×1017 Jones, which is about two or three order of magnitudes higher than that of the best devices available to date. |
