Atomic-scale Structural and Chemical Characterization of Hexagonal Boron Nitride Layers Synthesized at the Wafer-Scale with Monolayer Thickness Control
Wei-Hsiang Lin, Victor W. Brar, Deep Jariwala +5
Hexagonal boron nitride (h-BN) is a promising two-dimensional insulator with a large band gap and low density of charged impurities that is isostructural and isoelectronic with gra…
Spatially resolving density-dependent screening around a single charged atom in graphene
Dillon Wong, Fabiano Corsetti, Yang Wang +8
Electrons in two-dimensional graphene sheets behave as interacting chiral Dirac fermions and have unique screening properties due to their symmetry and reduced dimensionality. By u…
Electronically Tunable Perfect Absorption in Graphene
Seyoon Kim, Min Seok Jang, Victor W. Brar +2
Graphene nanostructures that support surface plasmons have been utilized to create a variety of dynamically tunable light modulators, motivated by theoretical predictions of the po…
Experimental Demonstration of >230° Phase Modulation in Gate-Tunable Graphene-Gold Reconfigurable Mid-Infrared Metasurfaces
Michelle C. Sherrott, Philip W. C. Hon, Katherine T. Fountaine +5
Metasurfaces offer significant potential to control far-field light propagation through the engineering of amplitude, polarization, and phase at an interface. We report here phase…
