Graphene with ultra-high carrier mobility and ultra-short photoresponse time has shown remarkable potential in ultrafast photodetection. However, the broad weak optical absorption (∼ 2.3%) of monolayer graphene hinders its practical application photodetectors high responsivity selectivity. Here we demonstrate that twisted bilayer graphene, a stack two monolayers an interlayer twist angle, exhibits strong light-matter interaction selectively enhanced photocurrent generation. Such enhancement...
