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…
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…
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…
