Disorder-driven symmetry suppression by van der Waals planar defects in a magnetic topological insulator
Rikkie Joris, Heyi Xia, Ana Beatriz Pedro Fontes +15
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…
Conductivity scaling of the anomalous Hall effect in the altermagnetic semiconductor α-MnTe
Sara Bey, Shelby S. Fields, Nicholas G. Combs +22
α-MnTe is a prototypical altermagnet exhibiting a strong anomalous Hall effect (AHE), despite having a nearly vanishing magnetization. Lately, sample-to-sample variations of the a…
RHEED pattern classification by a convolutional neural network for the growth of chalcogenide thin films and nanostructures
Nathan Muetzel, Viet Luu, Sara Bey +5
The use of reflection high energy electron diffraction (RHEED) plays a critical role for in-situ characterization in molecular beam epitaxy, pulsed laser deposition and sputtering.…
g-Factor Enhanced Upper Critical Field in Superconducting PdTe2 due to Quantum Confinement
Kota Yoshimura, Tzu-Chi Hsieh, Huiyang Ma +14
The Pauli limiting field of superconductors determines the maximal possible value of magnetic field at which superconductivity remains possible. For weak-coupling superconductors,…
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…
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…
