Defect‐Functionalization‐Mediated Tunneling Drives Nonlinear Photoemission in Perovskites
Advanced Science, EarlyView.This cover illustration depicts CsPbBr3 perovskite nanocrystals embedded with functionalized defect vacancies, where electrons migrate through defect‐mediated pathways and emit as lightning‐like beams. The imagery visualizes the core discovery of our work—defect‐functionalization‐mediated tunneling enabling nonlinear photoemission, where deep‐level ...

Grain Boundary‐Driven Lattice Dynamics in a Solid‐State Li‐Ion Conductor
Advanced Science, EarlyView.Grain boundaries in Li3OCl${\rm Li}_3{\rm OCl}$ are shown to significantly alter its lattice dynamics and induce Li‐ion vibrational hardening and anion softening. These changes hinder ion transport while promoting electronic conductivity and instability.
