摘要:

理解材料的结构-性质关系是凝聚态物理和材料科学中的基础问题。在过去的几年里,机器学习(ML)已经作为一种强大的工具,推动了这一理解并加速了材料发现。早期的ML方法主要集中在构建和筛选大规模材料空间,以识别各种应用中的有前景的候选材料。近年来,研究重点逐渐转向使用端到端生成模型生成晶体结构。本文综述了当前晶体结构预测和从头生成中生成模型的状态。它分析了晶体表示,概述了用于设计晶体结构的生成模型,并评估了它们各自的优势和限制。此外,本文还强调了评估生成结构的实验考虑因素,并提供了适合现有软件工具的建议。新兴主题,如建模无序和缺陷、在高级表征中的整合、纳入合成可行性约束以及模型可解释性,都被探讨。最终,本文旨在为希望适应合适ML模型的实验科学家以及希望理解逆材料设计和发现独特挑战的ML专家提供信息。

英文摘要:

Understanding structure-property relationships in materials is fundamental in condensed matter physics and materials science. Over the past few years, machine learning (ML) has emerged as a powerful tool for advancing this understanding and accelerating materials discovery. Early ML approaches primarily focused on constructing and screening large material spaces to identify promising candidates for various applications. More recently, research efforts have increasingly shifted toward generating crystal structures using end-to-end generative models. This review analyzes the current state of generative modeling for crystal structure prediction and de novo generation. It examines crystal representations, outlines the generative models used to design crystal structures, and evaluates their respective strengths and limitations. Furthermore, the review highlights experimental considerations for evaluating generated structures and provides recommendations for suitable existing software tools. Emerging topics, such as modeling disorder and defects, integration in advanced characterization, incorporating synthetic feasibility constraints, and model explainability are explored. Ultimately, this work aims to inform both experimental scientists looking to adapt suitable ML models to their specific circumstances and ML specialists seeking to understand the unique challenges related to inverse materials design and discovery.
