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…
Theoretical study of the conductance of ferromagnetic atomic-sized contacts
M. Häfner, J. K. Viljas, D. Frustaglia +4
Recently, different experiments on the transport through atomic-sized contacts made of ferromagnetic materials have produced contradictory results. In particular, several groups ha…
Theoretical analysis of the conductance histograms and structural properties of Ag, Pt and Ni nanocontacts
F. Pauly, M. Dreher, J. K. Viljas +3
Conductance histograms are a valuable tool to study the intrinsic conduction properties of metallic atomic-sized contacts. These histograms show a peak structure, which is characte…
Structure and conductance histogram of atomic-sized Au contacts
M. Dreher, F. Pauly, J. Heurich +3
Many experiments have shown that the conductance histograms of metallic atomic-sized contacts exhibit a peak structure, which is characteristic of the corresponding material. The o…
Energy estimates for weakly hyperbolic systems of the first order
Michael Dreher, Ingo Witt
For a class of weakly hyperbolic systems of the form D_t - A(t,x,D_x), where A(t,x,D_x) is a first-order pseudodifferential operator whose principal symbol degenerates like t^{l_*}…
