Fabrication of high-performance broadband photodetectors using 1D-2D hybrid electronic materials for IoT applications

Two-dimensional (2D) material-based photodetectors are promising due to their unique structures and great optoelectronic properties. In this study, we synthesized advanced 2D materials by combining 1D ZnO materials for the high performance photodetection. Initially, 2D materials such as Molybdenum diselenide (MoSe₂) and Tungsten diselenide (WSe₂) nanosheets were synthesized using liquid exfoliation method, subsequently added in the ZnO nanorods hydrothermal growth. Interestingly, there was perceptible modification in structural and optical properties were observed when the combine different 2D materials with ZnO materials. In particular, the MoSe₂-WSe₂-ZNRs combination exhibits excellent photo response of 23,000 compared with ZNRs (240). The present research work is promising approach towards to the synthesis of hybrid electronic materials for advanced photodetector device fabrications. We also extended to use these devices for real-time photo-sensing and applied in IoT applications.
