Optical control of conductivity type and valley polarization via persistent photoconductivity in (Pb,Sn)Se quantum wells
Alexander Kazakov, Gauthier Krizman, Valentine V. Volobuev +8
The ability to tune the Fermi level of semiconductors is at the heart of modern electronics. Here, we demonstrate that persistent photoconductivity (PPC) enables tuning of carrier…
Magneto-resistance quantum oscillations in a magnetic two-dimensional electron gas
J. Kunc, B. A. Piot, D. K. Maude +7
Magneto-transport measurements of Shubnikov-de Haas (SdH) oscillations have been performed on two-dimensional electron gases (2DEGs) confined in CdTe and CdMnTe quantum wells. The…
Fractional Quantum Hall Effect in a Diluted Magnetic Semiconductor
C. Betthausen, P. Giudici, A. Iankilevitch +9
We report the observation of the fractional quantum Hall effect in the lowest Landau level of a two-dimensional electron system (2DES), residing in the diluted magnetic semiconduct…
Quantum Hall states under conditions of vanishing Zeeman energy
F. J. Teran, M. Potemski, D. K. Maude +4
We report on magneto-transport measurements of a two-dimensional electron gas confined in a CdMnTe quantum well structure under conditions of vanishing Zeeman e…
Fractional quantum Hall effect in CdTe
B. A. Piot, J. Kunc, M. Potemski +6
The fractional quantum Hall (FQH) effect is reported in a high mobility CdTe quantum well at mK temperatures. Fully-developed FQH states are observed at filling factor 4/3 and 5/3…
Magnetization dynamics down to zero field in dilute (Cd,Mn)Te quantum wells
Mateusz Goryca, David Ferrand, Piotr Kossacki +8
The evolution of the magnetization in (Cd,Mn)Te quantum wells after a short pulse of magnetic field was determined from the giant Zeeman shift of spectroscopic lines. The dynamics…
