Enhanced linear and symmetric synaptic weight update characteristics in a Pt/p-LiCoOx/p-NiO/Pt memristor through interface energy barrier modulation by Li ion redistribution

A memristor with a Pt/p-LiCoO x /p-NiO/Pt structure exhibited enhanced linear and symmetric conductance changes for synaptic weight update, which was driven by interface energy barrier modulation as a result of Li ion redistribution.
