Tae Soo Kim (first author) and Professor Ki Jun Yu (corresponding author) reported “Fast, Energy-Efficient InGaAs Synaptic Phototransistors on Flexible Substrate” on Advanced Electronic Materials (Impact Factor: 6.2).

This paper is the development of synaptic phototransistor superior to biological synapse, expected to be applied as an important neuromorphic device for optical communications, autonomous driving, and the night vision system.
