Experimental discovery of structure-property relationships in ferroelectric materials via active learning
Yongtao Liu, Kyle P. Kelley, Rama K. Vasudevan +3
Emergent functionalities of structural and topological defects in ferroelectric materials underpin an extremely broad spectrum of applications ranging from domain wall electronics…
Decoding the shift-invariant data: applications for band-excitation scanning probe microscopy
Yongtao Liu, Rama K. Vasudevan, Kyle Kelley +5
A shift-invariant variational autoencoder (shift-VAE) is developed as an unsupervised method for the analysis of spectral data in the presence of shifts along the parameter axis, d…
Super-R BiFeO: Epitaxial stabilization of a low-symmetry phase with giant electromechanical response
Oliver Paull, Changsong Xu, Xuan Cheng +9
Piezoelectrics interconvert mechanical energy and electric charge and are widely used in actuators and sensors. The best performing materials are ferroelectrics at a morphotropic p…
Autonomous Experiments in Scanning Probe Microscopy and Spectroscopy: Choosing Where to Explore Polarization Dynamics in Ferroelectrics
Rama K. Vasudevan, Kyle Kelley, Jacob Hinkle +4
Polarization dynamics in ferroelectric materials are explored via the automated experiment in Piezoresponse Force Spectroscopy. A Bayesian Optimization framework for imaging is dev…
Phenomenological description of bright domain walls in ferroelectric-antiferroelectric layered chalcogenides
Anna N. Morozovska, Eugene A. Eliseev, Kyle Kelley +3
Recently, a layered ferroelectric CuInP2Se6 was shown to exhibit domain walls with locally enhanced piezoresponse - a striking departure from the observations of nominally zero pie…
Unusual Electrical Conductivity Driven by Localized Stoichiometry Modification at Vertical Epitaxial Interfaces
Wenrui Zhang, Shaobo Cheng, Christopher M Rouleau +7
Precise control of lattice mismatch accommodation and cation interdiffusion across the interface is critical to modulate correlated functionalities in epitaxial heterostructures, p…
