Machine learning for automated experimentation in scanning transmission electron microscopy

npj Computational Materials, 2023
Machine learning (ML) has become critical for post-acquisition data analysis in (scanning) transmission electron microscopy, (S)TEM, imaging and spectroscopy. An emerging trend is the transition to real-time analysis and closed-loop microscope operation.
