Abstract
- In this paper, bias modulated synapse transistor based on ultrathin molybdenum disulfide (MoS2) was fabricated. By applying positive and negative pulses, the device can imitate the excitation and inhibition behaviors of natural synapse, respectively. The baseline and change percentage of postsynaptic current (PSC) can be tuned by the back-gate bias, enabling the reconfiguration of the weight profile in machine learning. The PSC change tendency between single pulse and multiple pulse tests is opposite, which is very useful to mimic natural synapse recovery feature. Besides, as MoS2 is utilized as channel materials, the device can be vertically scaled down to 2 nm, which is very hard for traditional materials. [ABSTRACT FROM AUTHOR]
