Disorder-driven symmetry suppression by van der Waals planar defects in a magnetic topological insulator
Rikkie Joris, Heyi Xia, Ana Beatriz Pedro Fontes +17
Magnetic topological insulators offer a platform to control electronic topology through magnetic order, yet reliable routes to tune their properties remain limited. Here, we show t…
Spectral analysis of the magneto-optical response in valley polarized PbSnSe
Xiaoqi Ding, Jiashu Wang, Mykhaylo Ozerov +7
Since the last century, considerable efforts have been devoted to the study of valley-degenerate narrow gap semiconductors, such as the PbSnSe alloy. This material poss…
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…
Energy gap of topological surface states in proximity to a magnetic insulator
Jiashu Wang, Tianyi Wang, Mykhaylo Ozerov +14
Topological surface-states can acquire an energy gap when time-reversal symmetry is broken by interfacing with a magnetic insulator. This gap has yet to be measured. Such topologic…
Observation of coexisting weak localization and superconducting fluctuations in strained Sn1-xInxTe thin films
Jiashu Wang, William Powers, Zhan Zhang +10
Topological superconductors have attracted tremendous excitement as they are predicted to host Majorana zero modes that can be utilized for topological quantum computing. Candidate…
Fermi level tuning and band alignment in Mn doped InAs/GaSb
Logan Riney, Joaquin Bermejo-Ortiz, Gauthier Krizman +10
InAs/GaSb hosts a broken gap band alignment that has been shown to generate helical topological edge states. Upon the introduction of Mn into the structure, it has been predicted t…
Epitaxial growth and magnetic characterization of EuSe thin films with various crystalline orientations
Ying Wang, Xinyu Liu, Seul-Ki Bac +6
We report different growth modes and corresponding magnetic properties of thin EuSe films grown by molecular beam epitaxy on BaF2, Pb1-xEuxSe, GaAs, and Bi2Se3 substrates. We show…
Topological response of the anomalous Hall effect in MnBi2Te4 due to magnetic canting
S. -K. Bac, K. Koller, F. Lux +15
Three-dimensional (3D) compensated MnBi2Te4 is antiferromagnetic, but undergoes a spin-flop transition at intermediate fields, resulting in a canted phase before saturation. In thi…
Introduction of Sr into Bi2Se3 thin films by molecular beam epitaxy
L. Riney, C. Bunker, S. -K. Bac +7
SrxBi2Se3 is a candidate topological superconductor but its superconductivity requires the intercalation of Sr by into the van-der-Waals gaps of Bi2Se3. We report the synthesis of…
Weak antilocalization beyond the fully diffusive regime in Pb1-xSnxSe topological quantum wells
Jiashu Wang, X. Liu, C. Bunker +9
We report the measurements and analysis of weak antilocalization (WAL) in Pb1-xSnxSe topological quantum wells in a new regime where the elastic scattering length is larger than th…
