Twist-angle dependence of the proximity spin-orbit coupling in graphene on transition-metal dichalcogenidesWe theoretically study the proximity spin-orbit coupling (SOC) in graphene on a transition-metal dichalcogenides (TMDC) monolayer stacked with arbitrary twist angles. We find that the relative ...
The recently discovered flat electronic bands and strongly correlated and superconducting phases in magic-angle twisted bilayer graphene (MATBG)1,2 crucially depend on the interlayer twist angle, θ. Although control of the global θ with a precision of about 0.1 degrees has been demonstrated1,2,...
an either 0° or 60° twist angle, which are geometrically equivalent between the as-grown MoS2and graphene. To further demonstrate the high quality and the clean surface of these MoS2domains, we further performed conductive AFM (C-AFM) imaging (Fig.1dand Supplementary Figure2). We can ...
A multiscale model is developed to predict the equilibrium structure of twisted bilayer, graphene (tBLG). Two distinct, modified Moire structures are observed. The breathing mode, stable at large twist angle, has small amplitude (opposite budding of the two layers. The bending mode is characteriz...
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”..
5a, the angle between the edges of the two hexagonal graphene layers is the interlayer twist angle. These methods are simple and convenient to measure the twist angle, but it has certain errors. Other measurement methods, such as, LEED, SAED [35], and fast Fourier transforms (FFT) of ...

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 ...
Structures made of rotated, ultra-thin materials provide a rich solid-state platform for designing novel devices. In particular, slightly twisted graphene layers have recently been shown to have exciting unconventional properties, that can ultimately lead to a new family of ma...
The latter—the twist angle between the two layers—provides a powerful tuning knob of the electronic properties of the heterostructure. Seminal results have been obtained in twisted bilayer graphene, where superconducting and correlated insulating states are created by fine control of the twist angle6...
