Efficient Hot Carrier Management in Lead Halide Perovskite Micro‐Disks Revealed by Super‐Diffusive Migration

open access: yesAdvanced Science, EarlyView.
Hot‐carrier transport in metal halide perovskites is investigated using spatiotemporally‐resolved photoluminescence microscopy. Mesa‐shaped MAPbBr3 microdisks exhibit anomalous super‐diffusive carrier propagation on nanosecond timescales, driven by hot‐carrier stabilization and strong carrier–phonon coupling.

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

open access: yesAdvanced Science, EarlyView.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

Orientation‐Engineered PtTe2 Schottky FETs: Quantum Transport Insights for Dopant‐Free Advanced Technology Nodes

open access: yesAdvanced Electronic Materials, EarlyView.
Monolayer PtTe2 enables dopant‐free Schottky FETs through its thickness‐dependent electronic transition. Quantum transport simulations show that crystallographic orientation strongly influences device performance, with Γ–M transport delivering higher drive current, lower leakage, and improved switching behavior.
