Microwave spectroscopy on a double quantum dot with an on-chip Josephson oscillator
A. W. Holleitner, H. Qin, F. Simmel +5
We present measurements on microwave spectroscopy on a double quantum dot with an on-chip microwave source. The quantum dots are realized in the two-dimensional electron gas of an…
Lateral tunneling through the controlled barrier between edge channels in a two-dimentional electron system
A. A. Shashkin, V. T. Dolgopolov, E. V. Deviatov +5
We study the lateral tunneling through the gate-voltage-controlled barrier, which arises as a result of partial elimination of the donor layer of a heterostructure along a fine str…
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…
Josephson Junctions defined by a Nano-Plough
B. Irmer, R. H. Blick, F. Simmel +3
We define superconducting constrictions by ploughing a deposited Aluminum film with a scanning probe microscope. The microscope tip is modified by electron beam deposition to form…
