Twisted bilayer graphene exhibits superconductivity and other electronic phenomena such as flat bands at specific orientations between the layers; however, the origins of the resulting electronic structure are complex. Here, the authors show theoreti

Recently, there has been a growing interest in do-it-yourself components to accelerate development of inexpensive fabrication approaches. Here, Chen et al.present a plasmon-assisted etching technique to fabricate planar optical components using array

Achieving fine control over the twist angles of stacked two-dimensional (2D) layers is critical for device fabrication. Here, we demonstrate that the interplay between lattice mismatch strain and f...

A major hurdle in understanding the phase diagram of twisted bilayer graphene (TBLG) are the roles of lattice relaxation and electronic structure on isolated band flattening near magic twist angles. In this work, the authors develop an accurate local

Isolated atomic planes can be assembled into a multilayer van der Waals (vdW) heterostructure in a precisely chosen sequence. These heterostructures feature moiré patterns if the constituent 2D material layers are stacked in an incommensurable way,

Three-dimensional simulations of a non-premixed microburner (channel height L z = 0.75 mm) are used to study flame structure and stability, for both H2–O2 and CH4–O2 mixtures, matching conditions of previously reported experiments. Thermal quench

We describe grain boundary structure and migration in graphene using the concept of dislocations in the displacement shift complete lattice. The equivalence of displacement shift complete lattice dislocations and grain boundary kinks in graphene is s

Interlayer rotation angles couple strongly to the electronic states of twisted van der Waals layers. However, not every angle is energetically favorable. Recent experiments on rotation-tunable electronics reveal the existence of a discrete set of ang
