TL;DR: In this article, angle-resolved photoemission spectroscopy was used to measure the band structure of free-standing exfoliated monolayer graphene, which exhibits out-of-plane deformation or corrugation.

TL;DR: In this paper, a large-area 30°-rotated bilayer graphene can be grown deterministically by chemical vapor deposition on Cu, eliminating the need of artificial assembly, and the quasicrystals are easily transferred to arbitrary substrates and integrated in high-quality hexagonal boron nitride-encapsulated heterostructures, which they process into dual-gated devices exhibiting carrier mobility up to 105 cm2/(V s).

TL;DR: In this paper, the exotic quantum transport behavior discovered in these materials, such as room temperature ballistic transport, unusual half-integer quantum Hall effect, and a non-zero Berrys phase in magneto-oscillations, are discussed in the connection to Dirac Fermion description in graphitic systems.

TL;DR: It is shown that the high mechanical sensitivity of an AFM cantilever can be exploited for imaging hyperbolic phonon polaritons in hBN, and this detection mechanism is in fact the first photonless detection of phonon Polaritons.

TL;DR: A scattering-type scanning near-field optical microscopy study of hexagonal boron nitride on black phosphorus (h-BN/BP) heterostructure is reported, demonstrating the first direct observation of in-plane anisotropic phonon polariton modes in vdW heterostructures and paves the way to novel nanophotonic devices and to a new way to characterize optical anisotropy in thin films.
