Anisotropic ionic transport-controlled synaptic weight update by protonation in a VO<sub>2</sub> transistor
Jaeseoung Park, Chadol Oh, Junwoo Son
Abstract
The control of field-driven ionic redistribution guided by crystal anisotropy increases the retention of H<sup>+</sup>s in VO<sub>2</sub> lattices by locating H<sup>+</sup> into the deep regions from the interfaces, and thus strengthens long-term memory in artificial synaptic devices.
