This project focuses on developing novel optoelectronic materials for neuromorphic synapse devices that emulate the learning and memory functions of biological synapses. The research involves designing and integrating light-responsive semiconductor materials, including organic and perovskite-based materials, into two-terminal device architectures. The optical and electrical properties of the materials will be investigated to achieve wavelength-dependent synaptic responses, plasticity, potentiation/depression, and memory behavior. The developed devices will be further evaluated for their potential in neuromorphic computing and artificial neural network applications, with the goal of enabling low-power, multifunctional, and optically controlled artificial synaptic systems.
