Engineered van der Waals crystal mimics neuronal cells with light-driven learning

A research team led by Professor Taesung Kim of the School of Mechanical Engineering at Sungkyunkwan University (SKKU) has developed an optoelectronic synaptic device that mimics the functions of human neurons and synapses at the device scale. The researchers designed a van der Waals (vdW) crystal through a single-step sulfurization process using mixed plasma. The device operates under optical stimuli, offering a structural solution for configuring semiconductor materials for brain-inspired computing.
