Description:

Reservoir computing (RC) is promising for achieving low power consumption neuromorphic devices. In this study, we have developed an all-solid-state electric double layer (EDL) transistor using multilayer MoS2 to realize high-performance physical reservoir computing (PRC). We have demonstrated high-performance of MoS2-based Raman-ion-gating reservoir (MoS2-RIGR), in which gate voltage-dependent resonant Raman scattering spectra of MoS2 were used as computational resources in addition to drain and gate current responses. Our device achieved good performance such as >97% accuracy in various nonlinear waveform transformations and 97.8% accuracy in solving a second-order nonlinear dynamic equation. Information processing capacity was evaluated to elucidate the origin of the high performance of our system.
