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…
Spontaneous Breaking of the SU(3) Flavor Symmetry in a Quantum Hall Valley Nematic
G. Krizman, A. Kazakov, C. -W. Cho +10
Two-dimensional quantum materials can host original electronic phases that arise from the interplay of electronic correlations, symmetry and topology. In particular, the spontaneou…
Wide Electrical Tunability of the Valley Splitting in a Doubly gated Silicon-on-Insulator Quantum Well
Nathan Aubergier, Vincent T. Renard, Sylvain Barraud +2
The valley splitting of 2D electrons in doubly-gated silicon-on-insulator quantum wells is studied by low temperature transport measurements under magnetic fields. At the buried th…
Magnetic phases and zone-folded phonons in a frustrated van der Waals magnet
A. Pawbake, F. Petot, F. Le Mardelé +14
2D magnetic materials have attracted extensive research interest due to their potential application in nanospintronics, optospintronics, and in magnonics. Ferromagnetic as well as…
Topological phase diagram and quantum magnetotransport effects in (Pb,Sn)Se quantum wells with magnetic barriers (Pb,Eu)Se
Alexander Kazakov, Valentine V. Volobuev, Chang-Woo Cho +6
In this study, we report here on a successful growth by molecular beam epitaxy of high crystalline quality PbSnSe:Bi/PbEuSe QWs with and $y =…
Probing Berry curvature in magnetic topological insulators through resonant infrared magnetic circular dichroism
Seul-Ki Bac, Florian le Mardelé, Jiashu Wang +16
Probing the quantum geometry and topology in condensed matter systems has relied heavily on static electronic transport experiments in magnetic fields. Yet, contact-free optical me…
