Nanoscopic Observation of Structural Changes After First‐Firing Behavior in W/GeTe/W Ovonic Threshold Switches Using AFM Tip–Based Local Biasing

Small Methods, EarlyView.
A local‐biasing system using AFM induces site‐specific threshold switching in Ge0.17Te0.83 films, enabling direct observation of crystalline/amorphous interface formation. First‐principles calculations reveal that this structural change induces Te 5p‐dominated mid‐gap states and electric field‐enhanced charge redistribution.

Redirecting Nano‐Silicon Agglomeration: Dual‐Carbon Design Triggers Self‐Adaptive Nanoporous Si Sponge for Enhanced Lithium Storage

Advanced Functional Materials, Volume 36, Issue 60, 27 July 2026.
This study addresses silicon anode degradation using an engineered nSi/Gr/C dual‐carbon matrix. By restricting SEI infiltration, the architecture redirects silicon agglomeration into a beneficial structural self‐adaptive activation. During cycling, silicon nanoparticles self‐organize into a resilient nanoporous sponge. This dynamic network accommodates
