| Abstract Scope |
Complex metal oxides' intricate structure-function relations lead to a wide range of tunable functional properties. Introducing disorder through amorphization provides additional opportunities to tune properties, particularly in the area of electrochemical energy storage and conversion [1]. Consequently, amorphous complex oxides have garnered growing interest with two primary goals: to harness their unique functional properties or to employ them as a chemically-flexible, far-from-equilibrium, thin-film processing platform that offers novel synthesis opportunities [2]. Relevant to these aims, we examine the processing-structure-function relationship for amorphous complex oxides by in situ solid-phase crystallization in the (scanning) transmission electron microscope. Atomic scale aspects of the processing are detailed, such as the evolution of structure and chemistry with temperature, and the corresponding effect on conductivity. Based on these insights, approaches to direct amorphous complex oxide processing towards desirable synthesis products are discussed.
