Description

To extract transferable insights from scanning transmission electron microscopy (STEM), one must deal with noise arising from electron scattering and of the investigated sample. This noise hinders a quantitative analysis of the observation, notably when the features of interest lie in the gradients of the raw data. Physics-informed neural networks have been proposed as a means to incorporate compliance with physical equations that are chosen a priori. We show here that phase field models can help to efficiently coarse-grain STEM video sequences of phase transformations.
