Research demonstrates enhanced electromechanical strains in ferroelectric multilayers, indicating superior material performance.
Large Strains from Small Materials In their Research Article (DOI: 10.1002/adma.202518417), Lane W. Martin and co-authors overcome substrate-induced limitations in the electromechanical response of thin films. By producing multilayer heterostructures based on domain-engineered ferroelectrics like PbZr0.2Ti0.8O3 it is possible to produce enhanced piezoelectric coefficients and maximum electromechanical strains that surpass the performance of bulk piezoceramics even in sub-100-nm films.
