近年来，人们对信息处理的需求日益增长，脑启发式神经形态器件得到了广泛的关注。突触器件作为一类重要的神经形态器件，在短短几年内迅速升温。在用于制备突触器件的各种材料中，半导体纳米晶体（NCs）因其优异的电学和光学性能而成为首选材料之一。本综述论文首先介绍了基于半导体纳米晶体的突触器件的研究背景及半导体纳米晶体的基本性质。然后，根据器件有源层所用纳米晶体种类的不同，分类介绍了基于纳米晶体的突触器件的最新研究进展。最后，讨论了基于半导体纳米晶体的突触器件目前仍面临的问题和挑战。

Abstract

To meet a growing demand for information processing

brain-inspired neuromorphic devices have been intensively studied in recent years. As an important type of neuromorphic device

synaptic devices have attracted strong attention. Among all the kinds of materials explored for the fabrication of synaptic devices

semiconductor nanocrystals (NCs) have become one of the preferred choices due to their excellent electronic and optical properties. In this review

we first introduce the research background of synaptic devices based on semiconductor NCs and briefly present the basic properties of semiconductor NCs. Recent developments in the field of synaptic devices based on semiconductor NCs are then discussed according to the materials employed in the active layers of the devices. Finally

we discuss existing problems and challenges of synaptic devices based on semiconductor NCs.
