Decorated electronic kagome lattice in twisted bilayer germanene
Dennis J. Klaassen, Rian A. M. Ligthart, Andrés R. Botello Mendez +10
Artificial kagome lattices provide a route to electronic flat bands, geometric frustration, and correlation driven phases, but their realization in atomically controlled two-dimens…
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…
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…
Moiré-modulated band gap and van Hove singularities in twisted bilayer germanene
Pantelis Bampoulis, Carolien Castenmiller, Dennis J. Klaassen +4
Twisting bilayers of two-dimensional topological insulators has the potential to create unique quantum states of matter. Here, we successfully synthesized a twisted bilayer of germ…
