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…
Stable integration of isolated cell membrane patches in a nanomachined aperture: a step towards a novel device for membrane physiology
N. Fertig, A. Tilke, R. H. Blick +3
We investigate the microscopic contact of a cell/semiconductor hybrid. The semiconductor is nanostructured with the aim of single channel recording of ion channels in cell membrane…
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…
Single-electron charging of self-assembled InAs quantum dots
M. Fricke, A. Lorke, M. Haslinger +3
The many-particle ground state and excitations of self-assembled InAs quantum dots are investigated using far-infrared (FIR) and capacitance spectroscopy. The contributions of quan…
Far-infrared and capacitance spectroscopy of self-assembled InAs quantum dots
A. Lorke, M. Fricke, B. T. Miller +4
We review a number of recent experiments which are probing ground state and excitations of few-electron systems in self-assembled InAs quantum dots. Far-infrared spectroscopy, toge…
