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…
Coherent canted ferrimagnetism and higher-order anisotropy in the nodal-line magnetic semiconductor Mn3Si2Te6
Chang-woo Cho, Beomtak Kang, Ildo Choi +9
The interplay between magnetic order and electronic topology in van der Waals materials enables extreme responses to external stimuli. The nodal-line semiconductor Mn3Si2Te6 exempl…
Magnetic-field-induced magnon portfolio in a van der Waals magnet
T. Riccardi, F. Le Mardélé, L. A. Veyrat de Lachenal +12
Magnonic excitations are investigated in chromium oxychloride (CrOCl), a van der Waal (vdW) antiferromagnet prone to a multitude of magnetic phase transitions, with absorption expe…
Paramagnetically driven superconducting re-entrance in Eu-doped infinite layer nickelates
Lucia Varbaro, Lukas Korosec, Chih-Ying Hsu +11
The breakthrough discovery of superconductivity in infinite-layer nickelates, and subsequently in several superconducting nickelates with more complex layered structures, capped a…
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…
