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 ...

Interface Synthesis By UHV Deposition/Diffusion Bonding

, 1996
An ultra high vacuum (UHV) deposition/bonding system has been constructed that can produce planar interfaces from a wide array of materials. The interfaces in this system can be synthesized in-situ by UHV diffusion bonding of two substrates with or ...

Electrolyte Design for Simultaneous Interfacial Stabilization in Si||NCM811 Full Cells

Advanced Science, EarlyView.
A dual‐additive electrolyte (DAEL) system was optimized to regulate interfacial reactions in both Si anode and the NCM811 cathode. DAEL suppresses gas evolution and degradation, enabling stable interphases. These synergistic effects enhance electrochemical stability and extend battery cycle life in high‐energy lithium‐ion cells.

Ferroelectric Behavior of Micro‐ to Submicron‐Scale HZO Capacitors: Impact of the Perimeter‐to‐Area Ratio

Advanced Electronic Materials, EarlyView.
Using C‐AFM, W/HZO/p‐Ge capacitors with areas down to 0.26 µm2 are investigated. Frequency‐dependent voltage ramps reveal switching currents that confirm complete polarization reversal across the entire electrode area, while PUND enables reconstruction of P–V loops.
