Wafer-Scale Vertical 1D GaN Nanorods/2D MoS/PEDOT:PSS for Piezophototronic Effect-Enhanced Self-Powered Flexible Photodetectors.

van der Waals (vdW) heterostructures constructed by low-dimensional (0D, 1D, and 2D) materials are emerging as one of the most appealing systems in next-generation flexible photodetection. Currently, hand-stacked vdW-type photodetectors are not compatible with large-area-array fabrication and show unimpressive performance in self-powered mode. Herein, vertical 1D GaN nanorods arrays (NRAs)/2D MoS/PEDOT:PSS in wafer scale have been proposed for self-powered flexible photodetectors arrays firstly.
