Moiré potentials substantially alter the electronic properties of twisted bilayer graphene at a magic twist angle. A propagating plasmon mode, which can be observed with optical nano-imaging, is associated with transitions between the moiré minibands.

All-optical modulation of second-harmonic generation in a monolayer molybdenum disulfide with a modulation depth of close to 100%, and speed limited only by the fundamental pulse duration, is achieved thanks to the crystal symmetry and the deep subwavelength thickness of the sample.

Carriers in a molybdenum disulfide transistor can be modulated without decreasing mobility by remote doping and charge transfer through a van der Waals heterostructure, which avoids dopant-induced impurity scattering in the channel.

In this study, we report the emergence of two-dimensional (2D) branching fractal structures (BFS) in the nanoconfinement between the active and the support layer of a thin-film-composite polyamide (TFC-PA) nanofiltration membrane. These BFS are crystal dendrites of NaCl formed when salts are either added to the piperazine solution during the...

When interactions between electrons in a material are strong, they can start to behave hydrodynamically. Spatially resolved imaging of current flow in a three-dimensional material suggests that electron–electron interactions are mediated by phonons.

Moiré trions are observed in electrostatically gated WSe2/MoSe2 heterobilayers, where photoluminescence polarization switching reveals a competition between valley-flip and spin-flip relaxation pathways of photo-excited carriers during trion formation.
