In article number 2005217, Jun He, Jie Jiang, and co‐workers demonstrate a novel neuromorphic photoelectric device of vertical van der Waals heterojunction phototransistor based on colloidal zero‐dimensional CsPbBr 3 ‐quantum‐dots/two‐dimensional MoS 2 heterojunction channel with a polymer ion‐gel electrolyte as the gate dielectric. Efficiency‐adjustable photoelectronic Pavlovian associative learning and photoelectronic‐hybrid neuronal gain modulation can be successfully achieved by utilizing the spatiotemporal and photoelectronic synergy approach.
