Area of Science:

  • Materials Science
  • Automation
  • Data Science

Background:

  • Self-driving laboratories (SDLs) integrate automation and machine learning for materials science.
  • Current SDLs are primarily optimization-driven, excelling at process tuning but offering limited physical insight.
  • Understanding synthesis-property relationships requires deeper mechanistic understanding, particularly concerning defect physics.

Purpose of the Study:

  • To introduce a complementary paradigm: exploration-driven, or scientific, SDLs for data generation.
  • To establish defect physics as a foundational principle for designing SDLs in inorganic optoelectronic materials.
  • To propose design principles for scientific SDLs that generate transferable and reusable datasets for mechanistic inference.

Main Methods:

  • Designing SDLs focused on generating data for data-driven science, rather than solely on performance optimization.
  • Systematically perturbing thermodynamic and kinetic synthesis variables.
  • Measuring defect-sensitive observables in parallel with synthesis variable manipulation.

    • Main Results:

    • Demonstrated the potential of exploration-driven SDLs using Cu2ZnSn(S,Se)4 as a case study.
    • Highlighted the scale of defect-aware materials exploration and limitations of current SDL paradigms.
    • Showcased how SDLs can generate structured datasets for mechanistic inference.

    Conclusions:

    • Scientific SDLs offer a new paradigm for materials science discovery by generating data close to the underlying physics.
    • Defect physics is central to designing effective SDLs for optoelectronic materials.
    • Well-designed SDLs can advance synthesis-aware materials design and enable mechanistic inference.
