Tunable atomically enhanced moiré Berry curvatures in twisted triple bilayer graphene
Konstantin Davydov, Ziyan Zhu, Noah Friedman +8
We report a twisted triple bilayer graphene platform consisting of three units of Bernal bilayer graphene consecutively twisted at 1.49° and 1.68°. We demonstrate the atomic recons…
Easy-to-configure zero-dimensional valley-chiral modes in a graphene point junction
Konstantin Davydov, Xi Zhang, Wei Ren +6
The valley degree of freedom in 2D materials can be manipulated for low-dissipation quantum electronics called valleytronics. At the boundary between two regions of bilayer graphen…
Electron Collimation in Twisted Bilayer Graphene via Gate-defined Moiré Barriers
Wei Ren, Xi Zhang, Ziyan Zhu +6
Electron collimation via a graphene pn-junction allows electrostatic control of ballistic electron trajectories akin to that of an optical circuit. Similar manipulation of novel co…
Unconventional domain tessellations in moiré-of-moiré lattices
Daesung Park, Changwon Park, Kunihiro Yananose +18
Imposing incommensurable periodicity on the periodic atomic lattice can lead to complex structural phases consisting of locally periodic structure bounded by topological defects. T…
