Cryogenic nano-imaging of second-order moiré superlattices
Niels C. H. Hesp, Sergi Batlle-Porro, Roshan Krishna Kumar +7
Second-order superlattices form when moiré superlattices of similar periodicities interfere with each other, leading to even larger superlattice periodicities. These crystalline st…
Transition from acoustic plasmon to electronic sound in graphene
David Barcons Ruiz, Niels C. H. Hesp, Hanan Herzig Sheinfux +10
Fermi liquids respond differently to perturbations depending on whether their frequency is larger (collisionless regime) or smaller (hydrodynamic regime) than the inter-particle co…
Transverse hypercrystals formed by periodically modulated phonon-polaritons
Hanan Herzig Sheinfux, Minwoo Jung, Lorenzo Orsini +10
Photonic crystals and metamaterials are two overarching paradigms for manipulating light. Combining the two approaches leads to hypercrystals: hyperbolic dispersion metamaterials t…
Engineering high quality graphene superlattices via ion milled ultra-thin etching masks
David Barcons Ruiz, Hanan Herzig Sheinfux, Rebecca Hoffmann +8
Nanofabrication research pursues the miniaturization of patterned feature size. In the current state of the art, micron scale areas can be patterned with features down to ~ 30 nm p…
High quality nanocavities through multimodal confinement of hyperbolic polaritons in hexagonal boron nitride
Hanan Herzig Sheinfux, Lorenzo Orsini, Minwoo Jung +15
A conventional optical cavity supports modes which are confined because they are unable to leak out of the cavity. Bound state in continuum (BIC) cavities are an unconventional alt…
