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…
Ultra-low-loss Polaritons in Isotopically Pure Materials: A New Approach
Alexander J. Giles, Siyuan Dai, Igor Vurgaftman +12
Conventional optical components are limited to size-scales much larger than the wavelength of light, as changes in the amplitude, phase and polarization of the electromagnetic fiel…
Mechanical detection and imaging of hyperbolic phonon polaritons in hexagonal Boron Nitride
Antonio Ambrosio, Luis A. Jauregui, Siyan Dai +7
Mid-infrared nano-imaging and spectroscopy of two-dimensional (2D) materials have been limited so far to scattering-type Scanning Near-field Optical Microscopy (s-NSOM) experiments…
Imaging of anomalous internal reflections of hyperbolic phonon-polaritons in hexagonal boron nitride
Alexander J Giles, Siyuan Dai, Orest J Glembocki +10
We use scanning near-field optical microscopy to study the response of hexagonal boron nitride nanocones at infrared frequencies, where this material behaves as a hyperbolic medium…
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…
Ferromagnetism and infrared electrodynamics of GaMnAs}
B. C. Chapler, S. Mack, R. C. Myers +7
We report on the magnetic and the electronic properties of the prototype dilute magnetic semiconductor GaMnAs using infrared (IR) spectroscopy. Trends in the ferromagne…
