Ferroelectric Switching in ZnO/Zn1-xMgxO Heterostructures: Atomistic Insights into Interfacial Coupling and Layer Architecture
Alireza Sepehrinezhad, Ali Mohammadi Dinani, Ece Gunay +4
Ferroelectric switching in heterostructures couples composition, layer topology, temperature, and interfacial boundary conditions. ReaxFF molecular dynamics isolates these variable…
Heterogeneous ferroelectricity and conductivity of oxidized BaTiO crystals: the role of nanoscale phase segregation in the surface region
Christian Rodenbücher, Gustav Bihlmayer, Susan Trolier-McKinstry +3
We investigate the effect of thermal oxidation on BaTiO single crystals. Our results reveal that, even at moderate temperatures of up to 1000 °C, complex segregation mechanisms…
An Automated Magnetron Sputtering Chamber for Ferroelectric Thin Film Deposition
Stanislav A. Udovenko, Ian Mercer, Sarah Olandt +5
Optimization of next-generation materials synthesis and manufacturing processes can be accelerated by effective use of digital datasets. However, a majority of existing custom rese…
Closed-loop discovery of out-of-distribution processing protocols by evolutionary search and uncertainty-aware learning
Yu Liu, Stanislav Udovenko, Ching-Che Lin +4
Many materials and chemical systems exhibit history-dependent responses, where functional outcomes are governed not only by final-state variables but by the time-dependent sequence…
Material-Limited Switching in Nanoscale Ferroelectrics
Tony Chiang, John J. Plombon, Megan K. Lenox +8
The ferroelectric switching speed has been experimentally obfuscated by the interaction between the measurement circuit and the ferroelectric switching itself. This has prohibited…
Quantitative Nonlinear Optical Polarimetry with High Spatial Resolution
Albert Suceava, Sankalpa Hazra, Jadupati Nag +8
Nonlinear optical microscopy such as in the optical second-harmonic generation (SHG) modality has become a popular tool today for probing materials in the physical and biological s…
Nitrogen Vacancies Induce Fatigue in Ferroelectric
Walter J. Smith, Betul Akkopru-Akgun, Erdem Ozdemir +7
Wurtzite ferroelectrics (e.g., ) are being explored for high-temperature and emerging near-, or in-compute, memory architectures due to the material ad…
Indirect Tunneling Enabled Spontaneous Time-Reversal Symmetry Breaking and Josephson Diode Effect in TiN/AlO/HfZrO/Nb tunnel junctions
Shaoqing Ding, Jinyuan Yao, Zhen Bi +6
Josephson diode (JD) effect found in Josephson tunnel junctions (JTJs) has attracted a great deal of attention due to its importance for developing superconducting circuitry based…
Integration of Scanning Probe Microscope with High-Performance Computing: fixed-policy and reward-driven workflows implementation
Yu Liu, Utkarsh Pratiush, Jason Bemis +8
The rapid development of computation power and machine learning algorithms has paved the way for automating scientific discovery with a scanning probe microscope (SPM). The key ele…
Electrical Degradation in Dielectric and Piezoelectric Oxides: Review of Defect Chemistry and Associated Characterization Techniques
Pedram Yousefian, Betul Akkopru-Akgun, Clive A. Randall +1
The properties of dielectric and piezoelectric oxides are determined by their processing history, crystal structure, chemical composition, microstructure, dopants (or defect) distr…
Strain fluctuations unlock ferroelectricity in wurtzites
Steven M. Baksa, Simon Gelin, Seda Oturak +8
Ferroelectrics are of practical interest for non-volatile data storage due to their reorientable, crystallographically defined polarization. Yet efforts to integrate conventional f…
