Figure 1. (A) Schematic illustration of reward learning in the human brain; (B) Schematic illustration of the biological strengthened memory and suppressed memory at the synaptic level; (C) Schematic illustration of the RL neural network diagram for navigation; (D) Schematic of the biological memory diversification of the device. TEM images of (E) ZnO and (F) CdS/ZnO; (G) XRD spectra of ZnO (blue curve), CdS/ZnO (red curve), and CdS/ZnO after H₂O₂ treatment (light blue curve); (H) Photocurrent responses of pristine electrode, H₂S-treated electrode, and H₂O₂-treated electrode. PDF: Powder Diffraction Powder; RL: reinforcement learning; XRD: X-ray diffraction; TEM: transmission electron microscopy.
