Selectively enhanced photocurrent generation in twisted bilayer graphene with van Hove singularity

Selectively enhanced photocurrent generation in twisted bilayer graphene with van Hove singularity

Graphene has the high carrier mobility and short photoresponse time required for efficient photodetection, but broad and weak optical absorption are severe drawbacks. Here, the authors show that twisted bilayer graphene with van Hove singularities exhibits a strong light-matter interaction and selec...
