Interface, bulk and surface structure of heteroepitaxial altermagnetic α-MnTe films grown on GaAs(111)
Sara Bey, Maksym Zhukovskyi, Tatyana Orlova +7
Epitaxial MnTe films have recently seen a spur of research into their altermagnetic semiconducting properties. However, those properties may be extremely sensitive to structural an…
Unexpected Tuning of the Anomalous Hall Effect in Altermagnetic MnTe Thin Films
Sara Bey, Shelby S. Fields, Nicholas G. Combs +10
The discovery of an anomalous Hall effect (AHE) sensitive to the magnetic state of antiferromagnets can trigger a new era of spintronics, if materials that host a tunable and stron…
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…
MBE growth of axion insulator candidate EuIn2As2
Muhsin Abdul Karim, Jiashu Wang, David Graf +6
The synthesis of thin films of magnetic topological materials is necessary to achieve novel quantized Hall effects and electrodynamic responses. EuIn2As2 is a recently predicted to…
Discovery of a high-temperature antiferromagnetic state and transport signatures of exchange interactions in a Bi2Se3/EuSe heterostructure
Ying Wang, Valeria Lauter, Olga Maximova +10
Spatial confinement of electronic topological surface states (TSS) in topological insulators poses a formidable challenge because TSS are protected by time-reversal symmetry. In pr…
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…
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…
Layered transition metal dichalcogenides: promising near-lattice-matched substrates for GaN growth
Priti Gupta, A. A. Rahman, Shruti Subramanian +10
Most III-nitride semiconductors are grown on non-lattice-matched substrates like sapphire or silicon due to the extreme difficulty of obtaining a native GaN substrate. We show that…
