Influence of vibrations on electron transport through nanoscale contacts
Marius Bürkle, Janne K. Viljas, Thomas J. Hellmuth +4
In this article we present a novel semi-analytical approach to calculate first-order electron-vibration coupling constants within the framework of density functional theory. It com…
Ab-initio study of the thermopower of biphenyl-based single-molecule junctions
M. Bürkle, L. A. Zotti, J. K. Viljas +6
Employing ab-initio electronic structure calculations combined with the non-equilibrium Green's function technique, we study the dependence of the thermopower Q on the conformation…
Conduction mechanisms in biphenyl-dithiol single-molecule junctions
M. Bürkle, J. K. Viljas, A. Mishchenko +5
Based on density-functional theory calculations, we report a detailed study of the single-molecule charge-transport properties for a series of recently synthesized biphenyl-dithiol…
Molecular dynamics study of the thermopower of Ag, Au, and Pt nanocontacts
F. Pauly, J. K. Viljas, M. Bürkle +3
Using molecular dynamics simulations of many junction stretching processes we analyze the thermopower of silver (Ag), gold (Au), and platinum (Pt) atomic contacts. In all cases we…
Energy relaxation in graphene and its measurement with supercurrent
Juha Voutilainen, Aurelien Fay, Pasi Häkkinen +3
We study inelastic energy relaxation in graphene for low energies to find out how electrons scatter with acoustic phonons and other electrons. By coupling the graphene to supercond…
Self heating and nonlinear current-voltage characteristics in bilayer graphene
J. K. Viljas, A. Fay, M. Wiesner +1
We demonstrate by experiments and numerical simulations that the low-temperature current-voltage characteristics in diffusive bilayer graphene (BLG) exhibit a strong superlinearity…
