Decoding crystallography from high-resolution electron imaging and diffraction datasets with deep learning

Abstract: While machine learning has been making enormous strides in many technical areas, it is still massively underused in transmission electron microscopy. To address this, a convolutional neural network model was developed for reliable classification of crystal structures from small numbers of electron images and diffraction patterns with no preferred orientation. Diffraction data containing 571,340 individual crystals divided among seven families, 32 genera, and 230 space groups were used to train the network. Des… Show more

“…To establish the strongly correlated connection between spin and orbit in solids, further to understand the structure-activity relationship of energy materials, it is absolutely necessary to use machine learning algorithms in quantum chemistry techniques. Besides decoding the fundamental relationships behinds structure and properties, the breakthrough of technologies, including synchrotron radiation [85], neutron diffraction [86], spherical aberra- https://engine.scichina.com/doi/10.1016/j.jechem.2020.05.044 tion corrected scanning transmission electron microscope [87], and so on, also promote the research and development of energy materials.…”

The strength associated with each prediction is reported without a-priori or ab-initio-based knowledge 83,84 . By processing each pattern, the probability and prominence between crystal families reflects the underlying structural changes at each hyper pixel, between the presence of a nanoparticle and underlying grid.…”
