๐ค AI Summary
Current AI-driven crystal materials discovery faces persistent bottlenecks: poor generalizability, limited interpretability, and absence of experimental closed-loop validation. To address these challenges, this work establishes the first unified analytical framework that systematically reviews AI advances across four core tasksโproperty prediction, synthesis design, characterization assistance, and theoretical computation acceleration. It clarifies the alignment mechanisms between crystal representations (e.g., crystal graphs, electron density grids, atomic sequences) and deep learning architectures (e.g., graph neural networks, 3D convolutional networks, sequence models, multi-task learning). A comprehensive taxonomy is proposed, categorizing methods by model, dataset, and task, thereby delineating their scope and limitations. Finally, the paper identifies two critical frontiers for breakthrough: scalable representation learning and physics-informed modeling. This study provides a foundational methodology and technical roadmap for next-generation intelligent materials platforms. (149 words)
๐ Abstract
Crystalline materials, with symmetrical and periodic structures, exhibit a wide spectrum of properties and have been widely used in numerous applications across electronics, energy, and beyond. For crystalline materials discovery, traditional experimental and computational approaches are time-consuming and expensive. In these years, thanks to the explosive amount of crystalline materials data, great interest has been given to data-driven materials discovery. Particularly, recent advancements have exploited the expressive representation ability of deep learning to model the highly complex atomic systems within crystalline materials, opening up new avenues for fast and accurate materials discovery. These works typically focus on four types of tasks, including physicochemical property prediction, crystalline material synthesis, aiding characterization, and accelerating theoretical computations. Despite the remarkable progress, there is still a lack of systematic investigation to summarize their distinctions and limitations. To fill this gap, we systematically investigated the progress made in recent years. We first introduce several data representations of the crystalline materials. Based on the representations, we summarize various fundamental deep learning models and their tailored usages in various material discovery tasks. Finally, we highlight the remaining challenges and propose future directions.
