Visualizing Atomically-Layered Magnetism in CrSBr
Daniel J. Rizzo, Alexander S. McLeod, Caitlin Carnahan +10
Two-dimensional (2D) materials can host stable, long-range magnetic phases in the presence of underlying magnetic anisotropy. The ability to realize the full potential of 2D magnet…
Graphene/-RuCl: An Emergent 2D Plasmonic Interface
Daniel J. Rizzo, Bjarke S. Jessen, Zhiyuan Sun +16
Work function-mediated charge transfer in graphene/-RuCl heterostructures has been proposed as a strategy for generating highly-doped 2D interfaces. In this geometry, graphe…
Model for quantitative tip-enhanced spectroscopy and the extraction of nanoscale-resolved optical constants
Alexander S. McLeod, Priscilla Kelly, M. D. Goldflam +6
Near-field infrared spectroscopy by elastic scattering of light from a probe tip resolves optical contrasts in materials at dramatically sub-wavelength scales across a broad energy…
Gate-tuning of graphene plasmons revealed by infrared nano-imaging
Z. Fei, A. S. Rodin, G. O. Andreev +12
Surface plasmons are collective oscillations of electrons in metals or semiconductors enabling confinement and control of electromagnetic energy at subwavelength scales. Rapid prog…
