Towards Automating Structural Discovery in Scanning Transmission Electron Microscopy
Nicole Creange, Ondrej Dyck, Rama K. Vasudevan +2
Scanning transmission electron microscopy (STEM) is now the primary tool for exploring functional materials on the atomic level. Often, features of interest are highly localized in…
Bayesian learning of adatom interactions from atomically-resolved imaging data
Mani Valleti, Qiang Zou, Rui Xue +8
Atomic structures and adatom geometries of surfaces encode information about the thermodynamics and kinetics of the processes that lead to their formation, and which can be capture…
Latent mechanisms of polarization switching from in situ electron microscopy observations
Reinis Ignatans, Maxim Ziatdinov, Rama Vasudevan +3
In situ scanning transmission electron microscopy enables observation of the domain dynamics in ferroelectric materials as a function of externally applied bias and temperature. Th…
Fast Scanning Probe Microscopy via Machine Learning: Non-rectangular scans with compressed sensing and Gaussian process optimization
Kyle P. Kelley, Maxim Ziatdinov, Liam Collins +5
Fast scanning probe microscopy enabled via machine learning allows for a broad range of nanoscale, temporally resolved physics to be uncovered. However, such examples for functiona…
Exploring physics of ferroelectric domain walls via Bayesian analysis of atomically resolved STEM data
Christopher T. Nelson, Rama K. Vasudevan, Xiaohang Zhang +5
The physics of ferroelectric domain walls is explored using the Bayesian inference analysis of atomically resolved STEM data. We demonstrate that domain wall profile shapes are ult…
Exploration of lattice Hamiltonians for functional and structural discovery via Gaussian Process-based Exploration-Exploitation
Sergei V. Kalinin, Mani Valleti, Rama K. Vasudevan +1
Statistical physics models ranging from simple lattice to complex quantum Hamiltonians are one of the mainstays of modern physics, that have allowed both decades of scientific disc…
