Single-Electron Effects in a Coupled Dot-Ring System
L. Meier, A. Fuhrer, T. Ihn +3
Aharonov-Bohm oscillations are studied in the magnetoconductance of a micron-sized open quantum ring coupled capacitively to a Coulomb-blockaded quantum dot. As the plunger gate of…
Two-dimensional imaging of the spin-orbit effective magnetic field
L. Meier, G. Salis, E. Gini +2
We report on spatially resolved measurements of the spin-orbit effective magnetic field in a GaAs/InGaAs quantum-well. Biased gate electrodes lead to an electric-field distribution…
Optimized stray-field-induced enhancement of the electron spin precession by buried Fe gates
L. Meier, G. Salis, N. Moll +5
The magnetic stray field from Fe gates is used to modify the spin precession frequency of InGaAs/GaAs quantum-well electrons in an external magnetic field. By using an etching proc…
Stray-field-induced modification of coherent spin dynamics
L. Meier, G. Salis, C. Ellenberger +2
Electron spins in an InGaAs semiconductor quantum well are used as a magnetometer of magnetic stray-fields from patterned Fe stripes. Using time-resolved Faraday rotation, the cohe…
A high-pressure hydrogen time projection chamber for the MuCap experiment
J. Egger, D. Fahrni, M. Hildebrandt +21
The MuCap experiment at the Paul Scherrer Institute performed a high-precision measurement of the rate of the basic electroweak process of nuclear muon capture by the proton, $μ^-…
Gate tunability of stray-field-induced electron spin precession in a GaAs/InGaAs quantum well below an interdigitated magnetized Fe grating
L. Meier, G. Salis, C. Ellenberger +2
Time-resolved Faraday rotation is used to measure the coherent electron spin precession in a GaAs/InGaAs quantum well below an interdigitated magnetized Fe grating. We show that th…
