Description
Summary:In article number 1800195, Yuchao Yang and co‐workers demonstrate an ionic‐gating‐modulated synaptic transistor based on van der Waals crystals, showing bio‐realistic short‐term and long‐term plasticity along with remarkable linearity, symmetry, and ultralow energy consumption of ≈30 fJ per spike. 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.
