New neural network Multi4D maps material interfaces with 98.82% accuracy

Researchers have developed Multi4D, a novel neural network framework designed to analyze complex material interfaces using four-dimensional scanning transmission electron microscopy (4D-STEM). This system integrates a Diffusion Transformer with a convolutional neural network to accurately identify crystallographic structures, achieving 98.82% accuracy. Multi4D also introduces a metric called Diffraction-Inferred Structural Complexity to quantify local structural ambiguity. The framework has been successfully applied to map structures in superconductors, corroded alloys, and battery interfaces at nanometer resolution, offering a new paradigm for automated microscopy in materials science.
