Two-dimensional molybdenum disulfide artificial synapse with high sensitivity

Abstract This paper reports the fabrication of an artificial synapse (AS) based on two-dimensional molybdenum disulfide (MoS 2 ) film. The AS emulates important synaptic functions such as paired-pulse facilitation, spike-rate dependent plasticity, spike-duration plasticity and spike-number plasticity. spike voltage can mediate ion migration in gel to regulate conductance MoS channel, thereby realizing emulation More importantly, stably exhibits high sensitivity response stimuli (100 mV) low-energy consumption (∼33.5 fJ per spike). In addition, device some realizes expression Morse code. development this represents step toward constructing high-performance multifunctional neuromorphic system.
