Water induced bandgap engineering in nanoribbons of hexagonal boron nitride
Chen Chen, Yang Hang, Hui Shan Wang +13
Different from hexagonal boron nitride (hBN) sheets, the bandgap of hBN nanoribbons (BNNRs) can be changed by spatial/electrostatic confinement. It has been predicted that a transv…
Deep Subwavelength Topological Edge State in a Hyperbolic Medium
Lorenzo Orsini, Hanan Herzig Sheinfux, Yandong Li +9
Topological nanophotonics presents the potential for cutting-edge photonic systems, with a core aim revolving around the emergence of topological edge states. These states are prim…
Bound states in the continuum and long-range coupling of polaritons in hexagonal boron nitride nanoresonators
Harsh Gupta, Giacomo Venturi, Tatiana Contino +6
Bound states in the continuum (BICs) garnered significant for their potential to create new types of nanophotonic devices. Most prior demonstrations were based on arrays of dielect…

The unique physical, mechanical, chemical, optical, and electronic properties of hexagonal boron nitride (hBN) make it a promising two-dimensional material for electronic, optoelec…
Coherently amplified ultrafast imaging using a free-electron interferometer
Tomer Bucher, Harel Nahari, Hanan Herzig Sheinfux +18
Accessing the low-energy non-equilibrium dynamics of materials and their polaritons with simultaneous high spatial and temporal resolution has been a bold frontier of electron micr…
Unexpected catalytic activity of nanorippled graphene
P. Z. Sun, W. Q. Xiong, A. Bera +11
Graphite is one of the most chemically inert materials. Its elementary constituent, monolayer graphene, is generally expected to inherit most of the parent material's properties in…
Control of the phonon band gap with isotopes in hexagonal boron nitride
Paul Zeiger, Jordan Hachtel, Dominik Legut +5
The isotopic mass of constituent elements of materials has a well-known effect on the energy of vibrational modes. By means of monochromated scanning transmission electron microsco…
Dual-band coupling between nanoscale polaritons and vibrational and electronic excitations in molecules

Strong coupling (SC) between light and matter excitations such as excitons and molecular vibrations bear intriguing potential for controlling chemical reactivity, conductivity or p…
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…
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…
