Journal ArticleDOI
Local control of defects and switching properties in ferroelectric thin films
Sahar Saremi,Ruijuan Xu,Frances I. Allen,Joshua Maher,Joshua C. Agar,Ran Gao,Peter Hosemann,Lane W. Martin,Lane W. Martin +8 more
TL;DR: In this article, the role of point defects in ferroelectric-polarization switching was investigated and the authors provided systematic experimental evidence that point defects can be used to deterministically create and spatially locate point defects, resulting in small and symmetric changes in the coercive field.
Journal ArticleDOI
Revealing Ferroelectric Switching Character Using Deep Recurrent Neural Networks
Joshua C. Agar,Joshua C. Agar,Joshua C. Agar,Brett Naul,Shishir Pandya,Stefan van der Walt,Joshua Maher,Yao Ren,Long Qing Chen,Sergei V. Kalinin,Rama K. Vasudevan,Ye Cao,Joshua S. Bloom,Lane W. Martin,Lane W. Martin +14 more
TL;DR: This work demonstrates the efficacy of unsupervised neural networks in learning features of a material’s physical response from nanoscales multichannel hyperspectral imagery and provides new capabilities in leveraging in operando spectroscopies that could enable the automated manipulation of nanoscale structures in materials.
Journal ArticleDOI
Machine Detection of Enhanced Electromechanical Energy Conversion in PbZr0.2 Ti0.8 O3 Thin Films.
Joshua C. Agar,Ye Cao,Ye Cao,Brett Naul,Shishir Pandya,Stefan van der Walt,Aileen I. Luo,Joshua Maher,Nina Balke,Stephen Jesse,Sergei V. Kalinin,Rama K. Vasudevan,Lane W. Martin,Lane W. Martin +13 more
TL;DR: An automated workflow is developed to featurize, detect, and classify signatures of ferroelectric/ferroelastic switching processes in complex ferro electric domain structures, which enables the identification and nanoscale visualization of varied modes of response and a pathway to statistically meaningful quantification of the differences between those modes.
