Dual-gated graphene devices for near-field nano-imaging
Sai S. Sunku, Dorri Halbertal, Rebecca Engelke +11
Graphene-based heterostructures display a variety of phenomena that are strongly tunable by electrostatic local gates. Monolayer graphene (MLG) exhibits tunable surface plasmon pol…
Hyperbolic enhancement of photocurrent patterns in minimally twisted bilayer graphene
Sai S. Sunku, Dorri Halbertal, Tobias Stauber +10
Quasi-periodic moiré patterns and their effect on electronic properties of twisted bilayer graphene (TBG) have been intensely studied. At small twist angle , due to atomic recon…
Moiré metrology of energy landscapes in van der Waals heterostructures
Dorri Halbertal, Nathan R. Finney, Sai S. Sunku +20
The emerging field of twistronics, which harnesses the twist angle between two-dimensional materials, represents a promising route for the design of quantum materials, as the twist…
Nano-photocurrent mapping of local electronic structure in twisted bilayer graphene
Sai S. Sunku, Alexander S. McLeod, Tobias Stauber +10
We report a combined nano-photocurrent and infrared nanoscopy study of twisted bilayer graphene (TBG) enabling access to the local electronic phenomena at length scales as short as…
