| Abstract Scope |
This work explores how Large Language Models (LLMs) can enhance machine learning for materials synthesis and design, particularly in data-scarce cases. First, we apply LLMs to improve machine learning of chemical vapor deposition (CVD) of graphene on a limited, heterogeneous dataset collected from various studies in the literature. Our approach uses LLM-driven data imputation and LLM-generated embeddings to represent complex substrate nomenclature, boosting support vector machine (SVM) classification accuracy for number of graphene layers from 39% to 65% (binary) and from 52% to 72% (ternary). Besides LLM approaches to overcome data scarcity challenges in materials machine learning, we introduce an LLM-integrated ecosystem that combines language models with knowledge graphs to extract trends and generate novel synthesis hypotheses. Using this system, we map a two-decade roadmap of diamond CVD synthesis, identifying potential pathways for future exploration. |
