48‐3: In‐Ga‐Zn‐O Synaptic Transistor with 1 µm Channel Length for Neuromorphic Computing

Abstract

In this paper, indium‐gallium‐zinc‐oxide synaptic transistors with different channel lengths ranging from 2 μm to 1 μm were demonstrated. Channel scaling effect on synaptic behaviors such as long‐term depression and long‐term potentiation was investigated. A spiking neural network simulation was conducted to verify our synaptic transistor with a channel length of 1 μm, achieving high classification accuracy of 98.05%.
