Evolutionary Metal Oxide Clusters for Novel Applications: Toward High-Density Data Storage in Nonvolatile Memories

Abstract

Because of current fabrication limitations, miniaturizing nonvolatile memory devices for managing the explosive increase in big data is challenging. Molecular memories constitute a promising candidate for next-generation memories because their properties can be readily modulated through chemical synthesis. Moreover, these memories can be fabricated through mild solution processing, which can be easily scaled up. Among the various materials, polyoxometalate (POM) molecules have attracted considerable attention for use as novel data-storage nodes for nonvolatile memories. Here, an overview of recent advances in the development of POMs for nonvolatile memories is presented. The general background knowledge of the structure and property diversity of POMs is also summarized. Finally, the challenges and perspectives in the application of POMs in memories are discussed.

The application of clusters of polyoxometalates (POMs) in electronic devices, particularly in memory devices is discussed. The multielectron redox behavior and high chemical stability and tenability, as well as the compatibility with nanoscale-level scaling-down techniques are impressive figures of merits. POMs can be used in a wide range of fields, from chemistry to catalysis, and from memory devices to energy-storage devices.
