An international research collaboration has resulted in a breakthrough in the field of iontronics, leading to the development of faster thin film devices that promise improved batteries and advances in computing technology.
The team has created T-Nb2O5 thin films, allowing for the rapid movement of Li ions along 2D vertical channels, causing a significant transition from insulator to metal. This phenomenon is symbolized by various colored polyhedra and spheres in the accompanying illustrations.
Scientists from institutions including the Max Planck Institute of Microstructure Physics in Germany, the University of Cambridge in the UK, and the University of Pennsylvania in the USA have realized single-crystalline T-Nb2O5 thin films with two-dimensional vertical ionic transport channels. This allows for fast and noticeable insulator-metal transitions through Li-ion intercalation.
Niobium oxide, specifically T-Nb2O5, has been studied since the 1940s for its potential in enhancing battery efficiency. Its unique properties enable the quick movement of lithium ions, vital to battery operation, leading to faster charging.
The challenge lay in growing this specific niobium oxide material into high-quality thin films, due to its complex structure and the existence of various similar forms. However, in a paper published in Nature Materials, the researchers succeeded in growing high-quality, single-crystal thin films of T-Nb2O5, facilitating faster movement of lithium ions.
The significant electrical change that the T-Nb2O5 films undergo as a result of Li insertion translates into a dramatic decrease in resistivity, demonstrating the potential for tunable and low voltage operation of thin film devices.
The collaborative efforts of the research groups have allowed for the growth of single-crystalline T-Nb2O5 thin films, showing how Li-ion intercalation can drastically increase their electrical conductivity. Furthermore, they’ve discovered several previously unknown transitions in the material’s structure, enabling a switch from insulator to metal.
This research not only involved the expertise of the three international groups in areas of thin films, batteries, and theoretical insights but also was supported by various grants and institutions.
The first author, Hyeon Han, highlights the potential of T-Nb2O5 for future electronics and energy storage solutions. Andrew Rappe emphasizes the significant boost in the speed of ion movement, while Clare P. Grey notes the importance of controlling the orientation of the films. Stuart S. P. Parkin acknowledges the role of interdisciplinary collaboration in enhancing the understanding of complex materials, possibly leading to a more sustainable future by harnessing the intriguing field of iontronics.
The study, entitled “Li iontronics in single-crystalline T-Nb2O5 thin films with vertical ionic transport channels,” was published on July 27, 2023, in Nature Materials, and supported by various organizations, including the European Union’s Horizon 2020 program and the U.S. Department of Energy.
