The article discusses Graphene and two-dimensional materials has given a host of exciting new properties, including superconductivity and magnetism. Topics include superconductivity has thought to caused by interactions between electrons; and in magicangle graphene, the superlattice slows down enough that ...

“In this work, we studied the stacking of two layers of graphene and tungsten selenide (WSe2),” explained Ikerbasque Research Professor Félix Casanova, co-leader of the Nanodevices group at nanoGUNE and who led this work. “If the two layers are placed one on top of the other and rota...
two sheets of graphene are stacked on top of one another with a slight angular twist. In principle, at a certain “magic” twist angle, the speed of electrons in the material approaches zero, said
A University of Washington-led team has discovered that, by stacking a sheet of graphene onto bulk graphite at a small twist angle (top), “exotic” properties present at the graphene-graphite interface (yellow) can bleed down into the graphite itself. ...
Alternating twist multilayer graphene (ATMG) has recently emerged as a family of moiré systems that share several fundamental properties with twisted bilayer graphene, and are expected to host similarly strong electron–electron interactions near the magic angle. Here, we study alternating twist quadri...

The influence of twist angles on the thermal transport properties of bilayer graphene has attracted considerable attention within the scientific community. However, the relationship between twist angle and phonon hydrodynamics remains insufficiently explored. Additionally, the limitations of empirical potential ...
We consider a graphene bilayer with a relative small angle rotation between the layers--a stacking defect often seen in the surface of graphite--and calculate the electronic structure near zero energy in a continuum approximation. Contrary to what happens in an AB stacked bilayer and in accord ...
In twisted bilayer graphene (TwBLG), a periodic superlattice is formed by asymmetric lattice and twisted angles. Some new electron states appear between layers. As the twisted angles change, the energy difference between the Van Hove singularity also obviously changes. At this point, the optical ...
