PACE-SIMS: Checkpoint-Gated Autonomous SIMS Characterization with AI-Agent Quality Control
Anton V Ievlev, Heather Hare, Yiyang Li +1
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is widely used for local chemical investigations across a broad range of materials and systems. However, its operation is…
Rapid synthesis of dual-element isotope-enriched alpha-MoO3 crystals by reactive vapor transport
Ryan W. Spangler, Jacob M. Shusterman, Anton V. Ievlev +3
In this work, we develop a rapid reactive vapor transport technique to efficiently utilize limited isotopically pure precursors, particularly gaseous 18O2, and synthesize mm-scale,…
Polarization switching on the open surfaces of the wurtzite ferroelectric nitrides: ferroelectric subsystems and electrochemical reactivity
Yongtao Liu, Anton V. Ievlev, Eugene A. Eliseev +5
Binary ferroelectric nitrides are promising materials for information technologies and power electronics. However, polarization switching in these materials is highly unusual. From…
Electronic mobility, doping, and defects in epitaxial chalcogenide perovskite thin films
Jack Van Sambeek, Jessica Dong, Anton V. Ievlev +3
We present the electronic transport properties of (BZS) thin films grown epitaxially by gas-source molecular beam epitaxy (MBE). We observe n-type behavior in al…
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…
Coexistence and interplay of two ferroelectric mechanisms in Zn1-xMgxO
Jonghee Yang, Anton V. Ievlev, Anna N. Morozovska +7
Ferroelectric materials promise exceptional attributes including low power dissipation, fast operational speeds, enhanced endurance, and superior retention to revolutionize informa…
