Low dimensional materials and devices for neuromorphic computing

The nonvolatile and continuous tuning of device conductance is the crucial requirement when developing novel materials and devices as artificial synapses. In this work we demonstrate that by exploiting various kinds of mechanisms such as ferroelectric tuning, floating gate controlling, ferroelectric-like transition in van der Waals layered 2-dimensional materials, electrokinetic phenomenon in nanofluid, etc. low dimensional devices have been successfully fabricated as memristive synapses. The advantages and challenges of using these low dimensional materials and devices as electronic synapses are illustrated with the hope of providing guidelines for the future development of this promising topic.
