Executive Summary : | The dielectric energy-storing devices are frequently used in high voltage level, the fast growing on the portable and wearable electronics have been increasing the demand on the energy-storing devices at finite electric field strength. The aim of this proposal is the demonstration of ultrahigh energy storage density, high efficiency at room temperature in the dielectric capacitor devices via domain wall engineering. Our approach is, confined the BiFeO3 layers with other dielectric materials such as SrTiO3 in a multilayer, superlattice design. The choice of this approach basically confined the BiFeO3 layer, thereby create exotic topological protected domain such as-vortex, skyrmion, flux-closure by playing the elastic energy and electrostatic energy and increasing the overall breakdown field strength of the device i.e. enhancing the energy density of the devices. Therefore, in this project, my team will conduct the research on the dielectric ultra-high-density storage and high efficiencies characteristics of the BiFeO3/SrTiO3 superlattice. |
