Dual‐Surface Reaction Enabled Organic–Inorganic Hybrid Photodiodes for Faint Light Detection and Imaging

open access: yesAdvanced Functional Materials, EarlyView.
This work proposes a dual‐surface reaction strategy to optimize the interfacial contacts in organic–inorganic photodetectors. 1,4,5,8,9,11‐hexaazatriphenylene hexacarbonitrile (HAT‐CN) and ytterbium layers are designed to react with the Si surface, thus minimizing noise.

Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.

In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

open access: yesAdvanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.
