Nature Materials, Published online: 19 April 2024; doi:10.1038/s41563-024-01874-4The authors report diode-like resistance in a non-magnetic topological insulator in the quantum Hall regime.

Nature Materials, Published online: 17 April 2024; doi:10.1038/s41563-024-01875-3The turn-off time is generally faster than the turn-on time in accumulation mode organic electrochemical transistors (OECTs), but the mechanism is less understood. Here the authors find different transient behaviours of turn-on and turn-off in accumulation mode OECTs, and...

Nature Materials, Published online: 16 April 2024; doi:10.1038/s41563-024-01862-8Ion exchange is a powerful method to access metastable materials for energy storage, but identifying lithium and sodium interchange in layered oxides remains challenging. Using such model materials, vacancy level and corresponding lithium preference are shown to be crucial...
