Plasmon excitations in mixed metallic nanoarrays
Kevin Conley, Neha Nayyar, Tuomas P. Rossi +4
We study the plasmonic properties of arrays of atomic chains which comprise noble (Cu, Ag, and Au) and transition (Pd, Pt) metal atoms using time-dependent density-functional theor…
Ab-initio transport fingerprints for resonant scattering in graphene
Karri Saloriutta, Andreas Uppstu, Ari Harju +1
We have recently shown that by using a scaling approach for randomly distributed topological defects in graphene, reliable estimates for transmission properties of macroscopic samp…
Stability of vortex structures in quantum dots
H. Saarikoski, S. M. Reimann, E. Rasanen +2
We study the stability and structure of vortices emerging in two-dimensional quantum dots in high magnetic fields. Our results obtained with exact diagonalization and density-funct…
Self-consistent study of electron confinement to metallic thin films on solid surfaces
E. Ogando, N. Zabala, E. V. Chulkov +1
We present a method for density-functional modeling of metallic overlayers grown on metallic supports. It offers a tool to study nanostructures and combines the power of self-consi…
Electron transport through quantum wires and point contacts
Paula Havu, Martti Puska, Risto Nieminen +1
We have studied quantum wires using the Green's function technique and the density-functional theory, calculating the electronic structure and the conductance. All the numerics are…
Vortex formation in quantum dots in high magnetic fields
H. Saarikoski, A. Harju, M. J. Puska +1
We study electronic structures of two-dimensional quantum dots in high magnetic fields using the density-functional theory (DFT) and the exact diagonalization (ED). With increasing…
