A novel method of storing data using the dielectric constant rather than electrical resistivity

"cubic perovskite substrate BaZrO3, boosts square-tensile-strain to BaTiO3 and promotes four-variants in-plane spontaneous polarization with oxygen vacancy creation... new platform for artificial design to a conceptual material system via heteroepitaxy inevitably combined with strain engineering. In addition, the switchable dielectric states provide evidence that the dielectric constant, rather than the electrical resistivity, can be considered a low-energy-consumption memory information"
