Moiré atoms and Wigner molecule (a) Schematic of moiré superlattice and (b) corresponding moiré potential at ϕ = 10°. Its minima, moiré atoms, form a triangular lattice. (c) Evolution of each of the ...

(Nanowerk News) Rydberg states occur in a range of physical systems including atoms, molecules, and solids. In particular, Rydberg excitons, which are highly energetic electron-hole pairs, were first ...

Phasons, low-temperature quasiparticles found in crystal lattices, help interlayer excitons move at ultra-low temperatures, offering insights for materials science and potential boosts to quantum tech ...

RIVERSIDE, Calif. -- When two similar atomic layers with mismatching lattice constants -- the constant distance between a layer's unit cells -- and/or orientation are stacked together, the resulting ...

Umklapp electron-electron scattering in so-called moiré superlattices made from aligned layers of 2D materials could degrade the high-temperature mobility of charge carriers. That’s the conclusion of ...

A moiré pattern appears when you stack and rotate two copies of an image with regularly repeating shapes, turning simple patterns of squares or triangles into a groovy wave pattern that moves across ...

Scientists have visualized the two parts of an elusive particle -- the moiré exciton -- to reveal its structure and unique properties. Published in leading journal Nature, scientists from the Okinawa ...

Band structure: Noninteracting band structure for pentalayer graphene at a displacement field energy of -40 meV. There is a wide gap between valence and conduction bands, and a zoomed-in view at right ...

Researchers have revisited one of the most ancient materials on Earth -- graphite, and discovered new physics that has eluded the field for decades. Researchers in the National Graphene Institute (NGI ...
