2D Vacancy Confinement in Anatase TiO2 for Enhanced Photocatalytic Activities

open access: yesAdvanced Materials, EarlyView.
A new strategy to spatially confine oxygen vacancy (VO) is demonstrated in the homo‐interface of anatase TiO2. The confined VO in anatase TiO2 not only exhibits metallic behavior with high carrier density and electron mobility, but also promotes photocarrier lifetime.

Strategies for Controlling Emission Anisotropy in Lead Halide Perovskite Emitters for LED Outcoupling Enhancement

open access: yesAdvanced Materials, EarlyView.
The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Modulating Trapping in Low‐Dimensional Lead–Tin Halides for Energy‐Efficient Neuromorphic Electronics

open access: yesAdvanced Materials, EarlyView.
Robust 2D Ruddlesden–Popper lead‐tin perovskites demonstrate exceptional resistive switching memory performance after cesium carbonate deposition, achieving a high accuracy of 90.1% in MNIST pattern recognition. Additionally, a novel energy‐efficient content‐addressable memory architecture, based on perovskite memristive devices, is proposed for ...

Conductive Polymer Coatings Control Reaction Selectivity in All‐Iron Redox Flow Batteries

open access: yesAdvanced Materials, EarlyView.
Aqueous redox flow batteries are limited by the competing hydrogen evolution reaction (HER) at their negative electrodes. In this work, conductive polymers are conformally coated on porous carbonaceous electrodes to improve the reaction selectivity of hybrid all‐iron redox flow batteries.
