Defect engineering in two-dimensional perovskite nanowire arrays by europium(iii) doping towards high-performance photodetection

Abstract

We demonstrate high-performance photodetectors based on Eu-doped 2D perovskite nanowire arrays. The pure crystallographic orientation enables efficient carrier transport and the doped Eu ions effectively suppress the trap density in the nanowire arrays. As a result, the optimized Eu-doped photodetectors show an excellent responsivity of 6.24 A W−1, an outstanding specific detectivity of 5.83 × 1013 Jones and stable photo-switching behavior with a current on/off ratio of 103.
