Tunable synaptic devices based on ambipolar MoTe2 transistor

Synapse is one of the main elements of hardware implementation in a neuron network. Complex CMOS technology-based circuits using various Si-based transistors, non-Si based memory devices like RRAM, and 2D FET devices serve as hardware implement for neuron network. In this work, we demonstrate ambipolar MoTe 2 FET devices with a wide range oftunability in synaptic characteristic and classical paired pulsed facilitation as well as spike-timing-dependent plasticity function.
