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…
Spin-orbit gaps in the s and p orbital bands of an artificial honeycomb lattice
J. J. van den Broeke, I. Swart, C. Morais Smith +1
Muffin-tin methods have been instrumental in the design of honeycomb lattices that show, in contrast to graphene, separated s and in-plane p bands, a p orbital Dirac cone, and a p…
p Orbital flat band and Dirac cone in the electronic honeycomb lattice
Thomas S. Gardenier, Jette J. van den Broeke, Jesper R. Moes +5
Theory anticipates that the in-plane px, py orbitals in a honeycomb lattice lead to new and potentially useful quantum electronic phases. So far, p orbital bands were only realized…
p-band engineering in artificial electronic lattices
M. R. Slot, S. N. Kempkes, E. J. Knol +7
Artificial electronic lattices, created atom by atom in a scanning tunneling microscope, have emerged as a highly tunable platform to realize and characterize the lowest-energy ban…
Edge-dependent topology in Kekulé lattices
S. E. Freeney, J. J. van den Broeke, A. J. J. Harsveld van der Veen +2
Topological states of matter are robust quantum phases, characterised by propagating or localised edge states in an insulating bulk. Topological boundary states can be triggered by…
Robust zero-energy modes in an electronic higher-order topological insulator: the dimerized Kagome lattice
S. N. Kempkes, M. R. Slot, J. J. van den Broeke +6
Quantum simulators are an essential tool for understanding complex quantum materials. Platforms based on ultracold atoms in optical lattices and photonic devices led the field so f…
Designer quantum states of matter created atom-by-atom
Alexander A. Khajetoorians, Daniel Wegner, Alexander F. Otte +1
With the advances in high resolution and spin-resolved scanning tunneling microscopy as well as atomic-scale manipulation, it has become possible to create and characterize quantum…
Design and characterization of electronic fractals
S. N. Kempkes, M. R. Slot, S. E. Freeney +4
The dimensionality of an electronic quantum system is decisive for its properties. In 1D electrons form a Luttinger liquid and in 2D they exhibit the quantum Hall effect. However,…
Experimental realization and characterization of an electronic Lieb lattice
Marlou R. Slot, Thomas S. Gardenier, Peter H. Jacobse +6
Geometry, whether on the atomic or nanoscale, is a key factor for the electronic band structure of materials. Some specific geometries give rise to novel and potentially useful ele…
Intermolecular contrast in atomic force microscopy images without intermolecular bonds
Sampsa K. Häm"aläinen, Nadine van der Heijden, Joost van der Lit +3
Intermolecular features in atomic force microscopy (AFM) images of organic molecules have been ascribed to intermolecular bonds. A recent theoretical study [P. Hapala et al., Phys.…
Electronic states in finite graphene nanoribbons: Effect of charging and defects
M. Ijäs, M. Ervasti, A. Uppstu +4
We study the electronic structure of finite armchair graphene nanoribbons using density-functional theory and the Hubbard model, concentrating on the states localized at the zigzag…
