| Abstract Scope |
The quest for novel materials with enhanced properties is ongoing. High entropy oxides (HEOs) have transformed material design by providing a vast compositional space and remarkable property tunability. These are multicomponent systems that consist of five or more cations randomly distributed within a solid solution. Since their discovery, HEOs have garnered significant attention for their potential applications in ionic conductors, magnetic materials, ferroelectrics, thermoelectrics, among others. Interestingly, the functional properties in HEOs can be tailored without changing the composition due to the presence of different cations that can adapt to multiple oxidation states. Here, we present our recent investigation of the local electronic and atomic structure determination in high entropy oxide nanostructures. This study utilizes advanced electron microscopy imaging and spectroscopy in addition to machine learning methods to provide insight into the chemical and atomic structure nuances in HEOs. This study provides great insight into the structure-property correlations in HEOs. |
