Abstract:
We present an easy noncovalent functionalization of MoS2-based photodetectors that results in an enhancement of the photoresponse by about four orders of magnitude, reaching responsivities up to 100 A W-1. The functionalization is technologically trivial, air-stable, fully reversible and reproducible, and opens the door to the combination of 2D-materials with molecular dyes for the development of high performance photodetectors.
