Chapter 20: Oxide Neuromorphic Transistors for Brain-like Computing

The brain surpasses traditional von Neumann computers in multiple ways, such as its efficiency in energy consumption and resilience to damage. This has garnered significant attention from researchers in recent years, leading to the development of brain-inspired computing and emerging neuromorphic devices. This includes both transistor-based and memristor devices. The focus of this chapter is on oxide transistor-based neuromorphic devices. The functions of biological synapses and neurons are briefly discussed, followed by an overview of the working mechanism and progress in oxide neuromorphic transistors, including electrolyte-gate oxide neuromorphic transistors, ferroelectric-gate oxide neuromorphic transistors, and floating-gate oxide neuromorphic transistors. The article concludes with a summary of the progress made and future prospects.
