Conductance through analytic constrictions
D. Koudela, A. -M. Uimonen, H. Häkkinen
We study the dependence of the intrinsic conductance of a nanocontact on its shape by using the recursion-transfer-matrix method. Hour-glass, torus, and spherical shapes are define…
Conductance through atomic point contacts between fcc(100) electrodes of gold
O. Lopez-Acevedo, D. Koudela, H. Häkkinen
Electrical conductance through various nanocontacts between gold electrodes is studied by using the density functional theory, scalar-relativistic pseudopotentials, generalized gra…
Lifshitz transitions and elastic properties of Osmium under pressure
Daniela Koudela, Manuel Richter, Arnulf Mobius +2
Topological changes of the Fermi surface under pressure may cause anomalies in the low-temperature elastic properties. Our density functional calculations for elemental Osmium evid…
