Microscopic origin of the conducting channels in metallic atomic-size contacts
J. C. Cuevas, A. Levy Yeyati, A. Martin-Rodero
We present a theoretical approach which allows to determine the number and orbital character of the conducting channels in metallic atomic contacts. We show how the conducting chan…

Conductance Quantization and Electron Resonances in Sharp Tips and Atomic-Size Contacts
A. Levy Yeyati, A. Martín-Rodero, F. Flores
The electronic and transport properties of atomic-size contacts are analyzed theoretically using a self-consistent tight-binding model. Our results show that, for s-like metals, a…
