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…
Guided Mid-IR and Near-IR Light within a Hybrid Hyperbolic-Material/Silicon Waveguide Heterostructure
Mingze He, Sami I. Halimi, Thomas G. Folland +6
Silicon waveguides have enabled large-scale manipulation and processing of near-infrared optical signals on chip. Yet, expanding the bandwidth of guided waves to other frequencies…
Quadratic to linear magnetoresistance tuning in TmB4
Sreemanta Mitra, Jeremy Goh Swee Kang, John Shin +7
The change of a material's electrical resistance (R) in response to an external magnetic field (B) provides subtle information for the characterization of its electronic properties…
