Photovoltage Enhancement in Twisted‐Bilayer Graphene Using Surface Plasmon Resonance

Enhanced photovoltages in twisted-bilayer graphene are obtained by adjusting twist angle and surface plasmon resonance. Results show that our metal–graphene–metal photodetector has incident-angle-dependent and polarization-dependent properties. The photovoltage intensities are related to the number of graphene layers and the twist angle. Twisted-bilayer graphene at the optimal incidence angle has an ≈700% enhanced photovoltage.
