Abstract

For the first time, we report high-performance two-dimensional (2D) perovskite Pb₂Nb₃O₁₀ photodetectors (PNO PDs). The few-layer PNO nanosheets are obtained successfully through a simple calcination and liquid exfoliation method. The individual PNO nanosheet devices with various structures (Au-PNO-Au, Au-PNO-Ti, Ti-PNO-Ti) are fabricated and investigated. The Au-PNO-Ti device exhibits a high rectification factor (∼10²) owing to a large Schottky barrier difference between the PNO nanosheet and two asymmetric electrodes. Notably, the Au-PNO-Ti device shows excellent self-powered performance, including high responsivity (2.8 A/W), high detectivity (1.1 × 10¹² Jones), and fast speed (0.2/1.2 ms) at 350 nm light illumination. This work not only suggests the performance of the PNO nanosheet PDs but also sheds light on the development of high-stability and high-performance devices based on 2D perovskite niobate in the future.
