Photodetectors Based on Van der Waals Heterostructures and Hybrid 2D Materials

Two-dimensional (2D) materials and van der Waals (vdW) heterostructures have shown tremendous potential for light detection applications, opening new avenues in the development of novel, high-performance and broadband photodetectors (PDs) beyond state-of-the-art. The rich portfolio of 2D materials and newly emerging physical phenomena in vdW heterostructures (e.g. twistronics, topology, strain engineering), together with favorable heterogeneous integration of 2D systems with silicon technology, CMOS read-out electronics and flexible platforms, set new horizons for the development of innovative 2D vdW PDs. The rise and widespread of new 2D PDs technology is expected to pave the way for advanced portable, wearable and smart devices, leading to major innovations in imaging, remote healthcare, disease diagnostics, food quality control, environmental sensing, automotive, and many more domains in our everyday life.
