摘      要：Photodetectors operating in the shortwave infrared region are of great significance due to their extensive applications in both commercial and military *** two-dimensional layered materials(2DLMs)are considered as the promising candidates for constructing nextgeneration high-performance infrared ***,the performance of 2DLMs-based photodetectors can hardly satisfy the requirements of practical applications due to their weak optical *** the present study,a strategy was proposed to design high-performance shortwave infrared photodetectors by integrating metalorganic frameworks(MOFs)nanoparticles with excellent optical absorption characteristics and 2DLM with high ***,this study demonstrated the practicability of this strategy in a MOF/2DLM(Ni-CAT-1/Bi_(2)Se_(3))hybrid heterojunction *** to the transfer of photo-generated carriers from the MOF to Bi_(2)Se_(3),the MOF nanoparticles integrated on the Bi_(2)Se_(3) layer can increase the photocurrent by 2-3 orders of *** resulting photodetector presented a high responsivity of 4725 A W^(−1) and a superior detectivity of 3.5×10^(13) Jones at 1500 *** outstanding performance of the hybrid heterojunction arises from the synergistic function of the enhanced optical absorption and photogating *** addition,the proposed device construction strategy combining MOF photosensitive materials with 2DLMs shows a high potential for the future high-performance shortwave infrared photodetectors.
