Accelerated search for BaTiO3-based piezoelectrics with vertical morphotropic phase boundary using Bayesian learning

This work combines informatics and materials knowledge using results from Landau–Devonshire theory to guide experiments in the design of lead-free piezoelectrics with desired properties, and predicts, synthesize, and characterize a solid solution that shows better temperature reliability than other BaTiO3-based piezOElectrics in initial training data.
