An international team finds new single-crystalline oxide thin films with fast and dramatic changes in electrical properties via Li-ion intercalation through engineered ionic transport channels.
Researchers have pioneered the creation of T-Nb2O5 thin films that enable faster Li-ion movement. This achievement, promising more efficient batteries and advances in computing and lighting, marks a significant leap forward in iontronics.
An international research team, comprising members from the Max Planck Institute of Microstructure Physics, Halle (Saale), Germany, the University of Cambridge, UK, and the University of Pennsylvania, USA, have reported an important breakthrough in materials science. They achieved the first realization of single-crystalline T-Nb2O5 thin films, exhibiting two-dimensional (2D) vertical ionic transport channels. This results in a swift and significant insulator-metal transition through Li-ion intercalation in the 2D channels.
