A Carbon Nanotube Synapse with Dynamic Logic and Learning (Adv. Mater. 12/2013)

A carbon nanotube (CNT) electronic synapse which emulates a biological synapse with its dynamic logic, learning, and memory functions is induced by the interactions between CNTs and hydrogen ions in an electrochemical cell. Temporally correlated spikes can trigger the dynamic interactions between CNTs and hydrogen ions, resulting in spike-timing dependent plasticity (STDP) for memory and learning, as reported by Yong Chen and co-workers page 1693.
