Autonomous Materials Synthesis by Machine Learning and Robotics

Abstract: Future materials-science research will involve autonomous synthesis and characterization, requiring an approach that combines machine learning, robotics, and big data. Here, we highlight our recent experiments in autonomous materials exploration. We show the synthesis and resistance minimization of Nb-doped TiO2 thin films as a proof of concept. The system fully automates sample transfer, thin film deposition, and growth condition optimization—all addressing the physical aspects of fabrication. Combining Bayesian optimization with robotics illustrates how the required speed and volume of a future big-data collection in materials science will be achieved and demonstrate the potential of this approach. We briefly discuss the outlook and significance of these results and discuss a new materials research style to accelerate materials science.
