Charge Density Waves and the Hidden Nesting of Purple Bronze KMoO
Lei Su, Chuang-Han Hsu, Hsin Lin +1
We introduce the first multiorbital effective tight-binding model to describe the effect of electron-electron interactions in this system. Upon fixing all the effective hopping par…
Boron and nitrogen doping in graphene antidot lattices
Søren J. Brun, Vitor M. Pereira, Thomas G. Pedersen
Bottom-up fabrication of graphene antidot lattices (GALs) has previously yielded atomically precise structures with sub-nanometer periodicity. Focusing on this type of experimental…
Nonlinear photocurrents in two-dimensional systems based on graphene and boron nitride
F. Hipolito, Thomas G. Pedersen, Vitor M. Pereira
DC photoelectrical currents can be generated purely as a non-linear effect in uniform media lacking inversion symmetry without the need for a material junction or bias voltages to…
Graphene kirigami as a platform for stretchable and tunable quantum dot arrays
D. A. Bahamon, Zenan Qi, Harold. S. Park +2
The quantum transport properties of a graphene kirigami similar to those studied in recent experiments are calculated in the regime of elastic, reversible deformations. Our results…
Piezoelectricity in planar boron nitride via a geometric phase
Matthias Droth, Guido Burkard, Vitor M. Pereira
Due to their low surface mass density, two-dimensional materials with a strong piezoelectric response are interesting for nanoelectromechanical systems with high force sensitivity.…
