Abstract

2D materials and specifically Transition Metal Dichalcogenides have received much attention as photoactive materials in photodetectors. These materials possess attractive properties, including a direct bandgap in the visible range and mechanical resilience to strain, making them an attractive material for flexible photodetectors. Here we demonstrate 4x4 pixel photodetector arrays on flexible and non-flexible substrates based on mechanically exfoliated flakes of MoS2. The arrays have a minimum pitch between array pixels of 9.5 µm in both vertical and horizontal directions. Demonstrating, to our knowledge, the densest 2D material based photodetector array to date.
