Mirror Symmetry Breaking and Lateral Stacking Shifts in Twisted Trilayer Graphene
Chao Lei, Lukas Linhart, Wei Qin +2
We construct a continuum model of twisted trilayer graphene using {\it ab initio} density-functional-theory calculations, and apply it to address twisted trilayer electronic struct…
Secondary Electron Emission by Plasmon Induced Symmetry Breaking in Highly Oriented Pyrolitic Graphite (HOPG)
Wolfgang S. M. Werner, Vytautas Astašauskas, Philipp Ziegler +4
Two-particle spectroscopy with correlated electron pairs is used to establish the causal link between the secondary electron spectrum, the plasmon peak and the unoccupied b…
Localized inter-valley defect excitons as single-photon emitters in WSe
L. Linhart, M. Paur, V. Smejkal +3
Single-photon emitters play a key role in present and emerging quantum technologies. Several recent measurements have established monolayer WSe as a promising candidate for a r…
Topologically non-trivial valley states in bilayer graphene quantum point contacts
Hiske Overweg, Angelika Knothe, Thomas Fabian +11
We present measurements of quantized conductance in electrostatically induced quantum point contacts in bilayer graphene. The application of a perpendicular magnetic field leads to…
