Enhanced quantized current driven by surface acoustic waves
J. Ebbecke, G. Bastian, M. Blöcker +2
We present the experimental realization of different approaches to increase the amount of quantized current which is driven by surface acoustic waves through split gate structures…
Comment on "Critical currents in ballistic two-dimensional InAs-based superconducting weak links"
G. Bastian
In ballistic Josephson junctions the experimentally observed iv-characteristics deviate from the theoretically predicted behaviour. Recently, Heida et al. Phys. Rev. B 60, 13135 (1…
Ballistic reflection at a side-gate in a superconductor-semiconductor-superconductor structure
G. Bastian, H. Takayanagi
We have fabricated a sub-micron-sized structure consisting of an InAs-based 2DEG, two narrow Nb leads and a gate, where the indirect ballistic transport between the non-oppositely…
Side-gate modulation of critical current in mesoscopic Josephson junction
Niels Asger Mortensen, Georg Bastian
We study the normal state conductance and the Josephson current in a superconductor-2DEG-superconductor structure where the size/shape of the 2DEG-region can be modified by an addi…
