The Order of Phase Transitions in Barrier Crossing
J. Bürki, C. A. Stafford, D. L. Stein
A spatially extended classical system with metastable states subject to weak spatiotemporal noise can exhibit a transition in its activation behavior when one or more external para…
Electronic and atomic shell structure in aluminum nanowires
A. I. Mares, D. F. Urban, J. Bürki +3
We report experiments on aluminum nanowires in ultra-high vacuum at room temperature that reveal a periodic spectrum of exceptionally stable structures. Two "magic" series of stabl…
Stability and Symmetry Breaking in Metal Nanowires
D. F. Urban, J. Bürki, C. A. Stafford +1
A general linear stability analysis of simple metal nanowires is presented using a continuum approach which correctly accounts for material-specific surface properties and electron…
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…
