Cloning of Zero Modes in One-Dimensional Graphene Superlattices
Wun-Hao Kang, Szu-Chao Chen, Ming-Hao Liu
One-dimensional (1D) graphene superlattices have been predicted to exhibit zero-energy modes a decade ago, but an experimental proof has remained missing. Motivated by a recent exp…
Valley splitter and transverse valley focusing in twisted bilayer graphene
Christophe De Beule, Peter G. Silvestrov, Ming-Hao Liu +1
We study transport in twisted bilayer graphene and show that electrostatic barriers can act as valley splitters, where electrons from the () valley are transmitted only to…
Electrostatic Superlattices on Scaled Graphene Lattices
Szu-Chao Chen, Rainer Kraft, Romain Danneau +2
A scalable tight-binding model is applied for large-scale quantum transport calculations in clean graphene subject to electrostatic superlattice potentials, including two types of…
The Electronic Thickness of Graphene
Peter Rickhaus, Ming-Hao Liu, Marcin Kurpas +10
The van-der-Waals stacking technique enables the fabrication of heterostructures, where two conducting layers are atomically close. In this case, the finite layer thickness matters…
Characterization of Hydrogen Plasma Defined Graphene Edges
Mirko K. Rehmann, Yemliha B. Kalyoncu, Marcin Kisiel +8
We investigate the quality of hydrogen plasma defined graphene edges by Raman spectroscopy, atomic resolution AFM and low temperature electronic transport measurements. The exposur…
