The dielectric genome of van der Waals heterostructures
Kirsten Andersen, Simone Latini, Kristian S. Thygesen
Vertical stacking of two-dimensional (2D) crystals, such as graphene and hexagonal boron nitride, has recently lead to a new class of materials known as van der Waals heterostructu…
Plasmons on the edge of MoS2 nanostructures
Kirsten Andersen, Karsten W. Jacobsen, Kristian S. Thygesen
Using ab initio calculations we predict the existence of one-dimensional (1D), atomically confined plasmons at the edges of a zigzag MoS2 nanoribbon. The strongest plasmon originat…
Plasmons in metallic monolayer and bilayer transition metal dichalcogenides
Kirsten Andersen, Kristian S. Thygesen
We study the collective electronic excitations in metallic single- and bilayer transition metal dichalcogenides (TMDCs) using time dependent density functional theory in the random…
Hybridization of quantum plasmon modes in coupled nanowires: From the classical to the tunneling regime
Kirsten Andersen, Kristian L. Jensen, N. Asger Mortensen +1
We present full quantum mechanical calculations of the hybridized plasmon modes of two nanowires at small separation, providing real space visualization of the modes in the transit…
Spatially resolved quantum plasmon modes in metallic nano-films from first principles
Kirsten Andersen, Karsten W. Jacobsen, Kristian S. Thygesen
Electron energy loss spectroscopy (EELS) can be used to probe plasmon excitations in nanostructured materials with atomic-scale spatial resolution. For structures smaller than a fe…
