Strong Strain-Induced Coupling between Nanomechanical Pillar Resonators
Juliane Doster, Simon Hoenl, Heribert Lorenz +2
Networks of coupled resonators are an ubiquitous concept in physics, forming the basis of synchronization phenomena, metamaterial formation, nonreciprocal behavior and topological…
Size-independent Young's modulus of inverted conical GaAs nanowire resonators
P. Paulitschke, N. Seltner, A. Lebedev +2
We explore mechanical properties of top down fabricated, singly clamped inverted conical GaAs nanowires. Combining nanowire lengths of 2-9 m with foot diameters of 36-935 nm yie…
Molecular states in a one-electron double quantum dot
A. K. Huettel, S. Ludwig, H. Lorenz +2
The transport spectrum of a strongly tunnel-coupled one-electron double quantum dot electrostatically defined in a GaAs/AlGaAs heterostructure is studied. At finite source-drain-vo…
Direct control of the tunnel splitting in a one-electron double quantum dot
A. K. Huettel, S. Ludwig, K. Eberl +1
Quasi-static transport measurements are employed on a laterally defined tunnel-coupled double quantum dot. A nearby quantum point contact allows us to track the charge as added to…
Nano-ploughed Josephson Junctions as on-chip Radiation Sources
B. Irmer, F. Simmel, R. H. Blick +4
A new technique is presented which enables the fabrication of highly transparent Josephson junctions in combination with mesoscopic devices. We utilize a modified AFM tip to plough…
Nanolithography by non-contact AFM induced local oxidation : Fabrication of tunneling barriers suitable for single electron devices
B. Irmer, M. Kehrle, H. Lorenz +1
We study local oxidation induced by dynamic atomic force microscopy (AFM), commonly called TappingMode AFM. This minimizes the field induced forces, which cause the tip to blunt, a…
