Their detailed investigations reveal two‐stage ionic‐gating effects, namely, surface adsorption and internal intercalation, causing different post‐stimulation diffusive dynamics and accounting for the observed varied plasticity. \textlessdiv class="center graphic__image"\textgreater\textlessa target="_blank" href="//wol-prod-cdn.literatumonline.com/cms/attachment/baa22613-73e6-4abb-a82a-7e5f88c22084/adma201870149-gra-0001-m.jpg"\textgreater\textlessimg class="figure__image" src="//wol-prod-cdn.literatumonline.com/cms/attachment/72e27b37-ca3c-4860-a048-419255c83ca2/adma201870149-gra-0001-m.png"\textgreater\textless/a\textgreater\textlessp class="caption-style"\textgreater\textless/p\textgreater
