Excellent electronic transport in heterostructures of graphene and monoisotopic boron-nitride grown at atmospheric pressure
J. Sonntag, J. Li, A. Plaud +4
Hexagonal boron nitride (BN), one of the very few layered insulators, plays a crucial role in 2D materials research. In particular, BN grown with a high pressure technique has prov…
Three-dimensional Near-field Analysis Through Peak Force Scattering-type Near-field Optical Microscopy
Haomin Wang, Jiahan Li, James H. Edgar +1
Scattering-type scanning near-field optical microscopy (s-SNOM) is instrumental in exploring polaritonic behaviors of two-dimensional (2D) materials at the nanoscale. A sharp s-SNO…
Refractive Index-Based Control of Hyperbolic Phonon-Polariton Propagation
Alireza Fali, Samuel T. White, Thomas G. Folland +7
Hyperbolic phonon polaritons (HPhPs) are generated when infrared photons couple to polar optic phonons in anisotropic media, confining long-wavelength light to nanoscale volumes. H…
Polariton Nanophotonics using Phase Change Materials
Kundan Chaudhary, Michele Tamagnone, Xinghui Yin +14
Polaritons formed by the coupling of light and material excitations such as plasmons, phonons, or excitons enable light-matter interactions at the nanoscale beyond what is currentl…
Giant oscillations in a triangular network of one-dimensional states in marginally twisted graphene
S. G. Xu, A. I. Berdyugin, P. Kumaravadivel +12
The electronic properties of graphene superlattices have attracted intense interest that was further stimulated by the recent observation of novel many-body states at "magic" angle…
High quality factor polariton resonators using van der Waals materials
Michele Tamagnone, Kundan Chaudhary, Christina M. Spaegele +6
We present high quality factor optical nanoresonators operating in the mid-IR to far-IR based on phonon polaritons in van der Waals materials. The nanoresonators are disks patterne…
