Topology of honeycomb nanoribbons revisited
Zebedeus F. Osseweijer, Lumen Eek, Harold J. W. Zandvliet +2
We present an in-depth study of end states in honeycomb nanoribbons, focusing on the interplay between nanoribbon termination, chiral symmetry, and complex next-nearest-neighbor ho…
Electric-field control of zero-dimensional topological states in ultranarrow germanene nanoribbons
Lumen Eek, Esra D. van 't Westende, Dennis J. Klaassen +3
Reversible, all-electric control of symmetry-protected zero-dimensional modes has been a long-standing goal. In buckled honeycomb lattices, a perpendicular field couples to the sta…
Electric field-induced spin-valley locking in twisted bilayer buckled honeycomb materials
Harold J. W. Zandvliet, Pantelis Bampoulis, Cristiane Morais Smith +1
A twisted honeycomb bilayer exhibits a moiré superstructure that is composed of a hexagonal arrangement of AB and BA stacked domains separated by domain boundaries. In the case of…
Realization of a one-dimensional topological insulator in ultrathin germanene nanoribbons
Dennis J. Klaassen, Lumen A. G. Eek, Alexander N. Rudenko +9
Realizing a one-dimensional (1D) topological insulator and identifying the lower dimensional limit of two-dimensional (2D) behavior are crucial steps toward developing high-density…
2024 roadmap on 2D topological insulators
Bent Weber, Michael S Fuhrer, Xian-Lei Sheng +22
2D topological insulators promise novel approaches towards electronic, spintronic, and quantum device applications. This is owing to unique features of their electronic band struct…
