Highly-Polarized Near-Infrared Photodetector Based on 2D Organic/Inorganic Van Der Waals Heterostructure.

ABSTRACT: Organic semiconductors have demonstrated exceptional performance due to their inherent advantages such as simple processability, and superior mechanical properties. Developing polarization-sensitive near-infrared (NIR) organic photodetectors is crucial for their application in target recognition, biological imaging, and wearable optoelectronics. However, high-performance NIR photon detection still faces challenges for organic materials, due to their intrinsic limitations including low carrier mobility, and poor exciton dissociation. Here, a polarization-sensitive NIR photodetector is demonstrated with a linear dichroic ratio of 5.3, employing a two-dimensional (2D) TiOPc single-crystal/graphene heterostructure. Remarkable absorption, optimized exciton diffusion of single crystal, and effic
