Abstract:
Artificial synapses in neuromorphic computing systems hold potential to emulate biological
synaptic plasticity to achieve brain-like computation and autonomous learning behaviors in
non-von-Neumann systems. 2D materials, such as graphene, graphene oxide, hexagonal
boron nitride, transition metal dichalcogenides, transition metal oxides, 2D perovskite, and
black phosphorous, have been explored to achieve many functionalities of biological synapses
due to their unique electronic, optoelectronic, electrochemical, and mechanical properties
that are lacking in bulk materials. This review features the current development in the
state-of-the-art artificial synaptic electronic devices based on 2D materials. The structures of
these devices are first discussed according to their number of terminals (two-, three-, four-,
and multi-terminals) and geometric layouts (vertical, horizontal, hybrid). Since different 2D
materials have been utilized to fabricate these devices, their underlying physical mechanisms
and principles are further discussed, and their artificial neuron synaptic functionalities
and performances are analyzed and contrasted. Finally, a summary of the current research
status and major achievements is concluded, and the outlooks and perspectives for this
emerging and vibrant field and the potential applications of these devices for neuromorphic
computing are presented.
