Semiconductors that can be made from liquid solutions could make electronics and quantum devices cheaper and easier to manufacture at scale. Metal halide perovskite nanocrystals, tiny crystals with excellent light and electronic properties, are a leading candidate.

What they work on
- Discover lead-free metal halide perovskite nanocrystals by running networked self-driving laboratories that pair automated flow chemistry with machine learning to choose experiments on their own.
- Expand the range of syntheses that can be explored using modular flow reactors with independently tunable reaction conditions for making semiconductor nanocrystals.
- Combine data from cloud-connected labs at multiple institutions using federated learning to predict how synthesis parameters control nanocrystal properties, and release the data as a public AI-ready database.
More about the research
Most of them, however, contain lead, a toxic heavy metal. Finding lead-free versions by ordinary trial and error could take years.
Why it matters
Lead-free perovskite nanocrystals could enable low-cost, solution-made semiconductors for electronics and quantum technologies without the toxicity concerns of lead. Faster AI-guided discovery and a shared public experimental database could help materials researchers and manufacturers find and scale up such materials much more quickly.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
