Spin Blockade in Capacitively Coupled Quantum Dots
M. C. Rogge, C. Fuhner, U. F. Keyser +1
We present transport measurements on a lateral double dot produced by combining local anodic oxidation and electron beam lithography. We investigate the tunability of our device an…
Direct Measurement of the g-Factor of Composite Fermions
F. Schulze-Wischeler, E. Mariani, F. Hohls +1
The activation gap of the fractional quantum Hall states at constant fillings and 2/5 has been measured as a function of the perpendicular magnetic field . A linear…
Combined atomic force microscope and electron-beam lithography used for the fabrication of variable-coupling quantum dots
M. C. Rogge, C. Fuehner, U. F. Keyser +4
We have combined direct nanofabrication by local anodic oxidation with conventional electron-beam lithography to produce a parallel double quantum dot based on a GaAs/AlGaAs hetero…
Phase measurements using Two-Channel Fano Interference in a Semiconductor Quantum Dot
C. Fuhner, U. F. Keyser, R. J. Haug +2
We investigate a lateral semiconductor quantum dot with a large number of electrons in the semi-open Fano regime. In transport measurements we observe three stable series of Fano r…
