Highly sensitive active pixel image sensor array driven by large-area bilayer MoS2 transistor circuitry

Abstract

Here, the authors report the realization of an active pixel image sensor array composed by 64 pairs of switching transistors and phototransistors, based on wafer-scale bilayer MoS2. The device exhibits sensitive photoresponse under RGB light illumination, showing the potential of 2D MoS2 for image sensing applications.
