Resonant Spin Amplification and Accumulation in MAPbI3 Single Crystals

open access: yesAdvanced Science, EarlyView.
Carrier spin dynamics are studied in a 20 µm thin MAPbI3 perovskite single crystal using time‐resolved Kerr ellipticity at cryogenic temperatures. Long spin relaxation (30 ns) and dephasing (21 ns) enable spin accumulation. Spin accumulation effects are discussed in detail along with carrier‐nuclear spin interactions.

Amorphous Engineering Driving d‐Orbital High Spin Configuration for Almost 100% 1O2‐Mediated Fenton‐Like Reactions

open access: yesAdvanced Science, EarlyView.
Through an amorphization strategy, the electronic structure of single‐atom Co is effectively modulated from a low spin state (Co‐CCN) to a high spin state (Co‐ACN). The rearrangement of the electronic configuration optimizes the d‐band center resulting in the selectivity of 1O2 with almost 100%.

An Ultrafast Charge‐Driven Topological Intercalation Prelithiation Strategy for Carbon‐Silicon Composite Anodes

open access: yesAdvanced Science, EarlyView.
In this work, an ultrafast topological intercalation prelithiation method capable of forming a uniformly 3D stable solid electrolyte interface (SEI) network on porous C/SiOx nanofiber anodes within mere 30 s is designed. The SEI significantly enhances the initial Coulombic efficiency of the anodes to 99.44%, and the corresponding batteries show a ...
