Excitation spectra of two correlated electrons in a quantum dot
T. Ihn, C. Ellenberger, K. Ensslin +4
Measurements and a theoretical interpretation of the excitation spectrum of a two-electron quantum dot fabricated on a parabolic Ga[Al]As quantum well are reported. Experimentally,…
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…
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…
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…
Two-subband quantum Hall effect in parabolic quantum wells
C. Ellenberger, B. Simovic, R. Leturcq +5
The low-temperature magnetoresistance of parabolic quantum wells displays pronounced minima between integer filling factors. Concomitantly the Hall effect exhibits overshoots and p…
Excitation spectrum of two correlated electrons in a lateral quantum dot with negligible Zeeman splitting
C. Ellenberger, T. Ihn, C. Yannouleas +4
The excitation spectrum of a two-electron quantum dot is investigated by tunneling spectroscopy in conjuction with theoretical calculations. The dot made from a material with negli…
