Abstract Scope |
Crystallographic structure identification underpins material property prediction, yet traditional analysis of one- and two-dimensional X-ray diffraction (1D/2D XRD) patterns remains laborious. We introduce the Auto Diffraction Pipeline (ADP), a synthetic data generator that converts CIFs into realistic 1D intensity profiles and 2D spot patterns under diverse conditions—including varied zone axes, atomic substitution and depletion, and mechanical loading. Leveraging ADP, we assemble expansive training datasets to train convolutional neural networks for high-throughput classification of the seven crystal systems and all 230 space groups. Our generalized deep learning model adapts to experimental scenarios via expedited learning techniques and an architecture optimized around Bragg’s Law, while interpretability analyses clarify its decision-making. Validation on experimental measurements, unseen materials, and perturbed cubic crystals demonstrates state-of-the-art accuracy and robust space-group identification. This work paves the way for automated, data-driven XRD analysis, empowering materials exploration at unprecedented scales. |
