A Sungkyunkwan University research team has developed an optoelectronic synaptic device that mimics the functions of human neurons and synapses at the device level, the university said Tuesday.
The team led by Kim Tae-sung, professor at the School of Mechanical Engineering, has designed a van der Waals (vdW) crystal through a single-step sulfurization process using mixed plasma.
The developed device operates under optical stimuli, offering a structural solution to configure semiconductor materials for brain-inspired computing.
A van der Waals crystal is a type of layered material in which atoms or molecules are held together mainly by van der Waals forces rather than strong chemical bonds such as ionic, covalent or metallic bonds.
