On the Stability and Structural Dynamics of Metal Nanowires
J. Bürki, C. A. Stafford
This article presents a brief review of the nanoscale free-electron model, which provides a continuum description of metal nanostructures. It is argued that surface and quantum-siz…
Electronic shell effects and the stability of alkali nanowires
D. F. Urban, J. Bürki, A. I. Yanson +4
Experimental conductance histograms for Na nanowires are analyzed in detail and compared to recent theoretical results on the stability of cylindrical and elliptical nanowires, usi…
Jahn-Teller Distortions and the Supershell Effect in Metal Nanowires
D. F. Urban, J. Bürki, C. -H. Zhang +2
A stability analysis of metal nanowires shows that a Jahn-Teller deformation breaking cylindrical symmetry can be energetically favorable, leading to stable nanowires with elliptic…
Comment on "Density Functional Simulation of a Breaking Nanowire"
C. A. Stafford, J. Burki, D. Baeriswyl
In a recent Letter, Nakamura et al. [Phys. Rev. Lett. 82, 1538 (1999)] described first principles calculations for a breaking Na nanocontact. Their system consists of a periodic on…
Cohesion and conductance of disordered metallic point contacts
J. Burki, C. A. Stafford, X. Zotos +1
The cohesion and conductance of a point contact in a two-dimensional metallic nanowire are investigated in an independent-electron model with hard-wall boundary conditions. All pro…
