In the considerable material exploration space, it is essential for material development to find new functional materials efficiently. In order to efficiently explore such new materials, we have developed an autonomous experiment system utilizing machine learning and robotics, which automatically performs measurement and analysis of thin film materials fabricated by RF magnetron sputtering, including XRD, Raman, UV-Vis, and SEM/EDS. The system then autonomously searches the material search space until the desired physical properties are obtained, repeating synthesis, evaluation, and prediction of the subsequent synthesis conditions by Bayesian optimization.
