A 2D‐3D Perovskite Memristor‐Based Light‐Induced Sensitized Neuron for Visual Information Processing

) with phenylethylammonium iodide (PEAI). The introduction of the 2D layer increases the migration energy barrier and restricts the diffusion of ions, thus enabling the modulation of the current decay and light responsivity. By leveraging the tunable decay and wavelength selectivity of the memristor, a light-induced sensitized neuron (LISN) with an enhanced firing frequency is developed using a fundamental circuit design. Furthermore, LISN, which exhibits improved temporal processing and long-term dependency management, are integrated into sensitized spiking neural networks (SSNNs) to demonstrate their superior classification capabilities. This study underscores the potential of LISN-based neuromorphic systems in visual information processing and offers new insights for applications in complex scenarios.
