The Quantum Interference Effect Transistor
D. M. Cardamone, C. A. Stafford, S. Mazumdar
We propose a new type of molecular transistor, the Quantum Interference Effect Transistor (QuIET), based on tunable current suppression due to quantum interference. We show that an…
Cohesion, Conductance, and Charging Effects in a Metallic Nanocontact
C. A. Stafford, F. Kassubek, J. Bürki +2
The conducting and thermodynamic properties of ballistic metallic nanocontacts with smooth shapes are investigated. All properties are related to the electronic scattering matrix,…
Surface Fluctuations and the Stability of Metal Nanowires
C. H. Zhang, F. Kassubek, C. A. Stafford
The surface dynamics and thermodynamics of metal nanowires are investigated in a continuum model. Competition between surface tension and electron-shell effects leads to a rich sta…
Cohesion and Stability of Metal Nanowires: A Quantum Chaos Approach
C. A. Stafford, F. Kassubek, H. Grabert
A remarkably quantitative understanding of the electrical and mechanical properties of metal wires with a thickness on the scale of a nanometer has been obtained within the free-el…
Statistics of quantum transport in metal nanowires with surface disorder
J. Burki, C. A. Stafford
Experimental conductance histograms built from several thousand successive breakings of sodium nanowires exhibit peaks up to rather high conductance values (100 x 2e^2/h). In this…
Kondo Impurity in a Mesoscopic Ring: Charge Persistent Current
H. -P. Eckle, H. Johannesson, C. A. Stafford
We study the influence of a magnetic impurity or ultrasmall quantum dot on the charge persistent current of a mesoscopic ring. The system consists of electrons in a one-dimensional…
