Key Points

  • Generated amorphous structures showed accuracy in short-range and medium-range order, along with diverse macroscopic properties.
  • Silica glass was effectively modeled at cooling rates of 10 −2 K/ps, demonstrating a ductile-to-brittle transition.
  • This diffusion model serves as a roadmap for simulating previously inaccessible amorphous materials quickly.
  • Extending to metallic glasses enabled reproduction of local structure and characteristics from both experimental and computational sources.

Abstract

Abstract Generative models show great promise for the inverse design of molecules and inorganic crystals, but remain largely ineffective within more complex structures such as amorphous materials. Here, we present a diffusion model that reliably generates amorphous structures up to 3 orders of magnitude times faster than conventional simulations across processing conditions, compositions, and data sources. Generated structures recovered the short- and medium-range order, sampling diversity, and macroscopic properties of silica glass, as validated by simulations and an information-theoretical strategy. Conditional generation allowed sampling large structures at low cooling rates of 10 −2 K/ps to uncover a ductile-to-brittle transition and mesoporous silica structures. Extension to metallic glassy systems accurately reproduced local structures and properties from both computational and experimental datasets, demonstrating how synthetic data can be generated from characterization results. Our methods provide a roadmap for the design and simulation of amorphous materials previously inaccessible to computational methods.
