High-performance deformable photoswitches with p-doped graphene as the top window electrode

Abstract

Deformable polymer photoswitches with p-doped single layer graphene as the top window electrode exhibit excellent photoresponse with an on/off ratio as high as 8.5 × 10⁵. The charge-transfer doping of graphene results in better charge separation and collection efficiency and the structure of the top electrode minimizes the dark current.
