Obiettivo
Two of the main drivers of worldwide economic growth and scientific development are the semiconductor/IC industry and the need for new energy resources. The need for alternate renewable sources of energy such as sunlight and wind power which are inherently discontinuous, poses new challenges for energy transport and storage. Although many of the materials used in the IC industry and in energy storage are similar, the research in their properties has been separated in two fields with very little interdisciplinary interaction. This proposal aims to cross this barrier and evaluate physical and electrical properties of transition metal oxides in their nanostructured form for non-volatile memory and energy storage applications. For this we will investigate how material production and physical properties influence electronic and ionic transport properties in these oxides. We propose to evaluate transition metal oxides, starting with simple binary oxides such as vanadium oxides and assess how material production and physical properties influence electrical and/or ionic transport properties. A first objective is to identify materials where resistive switching can be ascribed to correlated electron effects rather than oxygen or oxygen vacancy rearrangement. It is interesting to determine how these effects are influenced by size and confinement. This is done keeping in mind possible applications as switch/ memory elements. Some oxides are expected to show relatively high ionic mobility making them good candidates for alternate battery materials. For this, screening of ionic mobility of the intrinsic oxide and of Li in the oxide is to be investigated. Correlating oxygen mobility in the lattice with Li mobility can help better engineer materials for highly performing batteries.
