(Invited) Nanocrystalline Silicon Thin Film Transistors for Neuromorphic Applications

Abstract

This paper briefly reviews some of our recent work on the fabrication, modeling and characterization of neuromorphic circuits using nanocrystalline-silicon (nc-Si) thin-film transistors (TFTs) and memristive (resistive switch) devices (1-11). SPICE models of our fabricated devices are presented. Complex synaptic and learning behavior is demonstrated as a natural outcome of using these specific devices. The fabrication processes are consistent with the use of glass or flexible substrates. Therefore, the neuromorphic architecture may provide for information processing that is more efficient than that expected for conventional TFT circuitry.
