Intrinsic Even-Odd Thickness-Driven Anomalous Hall in Epitaxial MnBi2Te4 Thin Films
Debarghya Mallick, Simon Kim, An-Hsi Chen +12
We demonstrate precise control of magnetism in MnBi2Te4 thin films through careful synthesis by molecular beam epitaxy, achieving minimal defects and accurate layer thickness contr…
Active Learning for Tractable and Reproducible Pulsed Laser Deposition
Jackson S. Bentley, Christopher Rouleau, Ilia N. Ivanov +8
This paper shows how data-driven machine learning approaches can improve growth control, reproducibility, and physical insight in the pulsed laser deposition (PLD) growth of correl…
Nucleation and Antiphase Twin Control in BiSe via Step-Terminated AlO Substrates
Alessandro R. Mazza, Jia Shi, Gabriel A. Vázquez-Lizardi +18
The epitaxial synthesis of high-quality 2D layered materials is an essential driver of both fundamental physics studies and technological applications. BiSe, a prototypical…
Programmable phase selection between altermagnetic and non-centrosymmetric polymorphs of MnTe on InP via molecular beam epitaxy
An-Hsi Chen, Parul R. Raghuvanshi, Jacob Cook +19
Phase selecting nearly degenerate crystalline polymorphs during epitaxial growth can be challenging yet is critical to targeting physical properties for specific applications. Here…
Tunable High Spin Chern-Number Insulator Phases in Strained Sb Monolayer
Jacob Cook, Po-Yuan Yang, Theo Volz +8
High spin Chern-number insulators (HSCI) have emerged as a novel 2D topological phase of condensed matter that is beyond the classification of topological quantum chemistry. In thi…
Stoichiometry-induced ferromagnetism in altermagnetic candidate MnTe
Michael Chilcote, Alessandro R. Mazza, Qiangsheng Lu +22
The field of spintronics has seen a surge of interest in altermagnetism due to novel predictions and many possible applications. MnTe is a leading altermagnetic candidate that is o…
