【摘要】：二维材料异质结是由石墨烯、六方氮化硼、过渡金属二硫族化合物、黑磷等二维材料通过面内拼接或层间堆叠形成的,并由此可分为二维材料面内异质结和垂直异质结.二维材料面内异质结可以实现区域内载流子的特殊传输行为;而垂直异质结中的层间量子耦合效应能够导致新颖的物理特性,通过调节异质结构界面可调制器件的电学及光学性能.目前,随着电子器件、光电器件等对集成性、功能性的要求不断提高,二维材料异质结越来越多地受到研究者的关注,实现二维材料异质结结构(包括界面)的有效调控是构筑高性能、高集成器件的前提.本文主要对比各类二维材料异质结的制备方法,介绍主流的几类二维材料异质结基电子器件和光电器件的结构、工作原理和性能,展望有前景的新型制备方法,并指出二维材料异质结在实际应用中面临的挑战.
[Abstract]:Two-dimensional heterojunctions are formed from graphene, hexagonal boron nitride, transition metal disulfide compounds and black phosphorus by in-plane splicing or interlaminar stacking, which can be divided into two dimensional in-plane heterojunctions and vertical heterojunctions.The two-dimensional in-plane heterojunction can realize the special transport behavior of the carriers in the region, and the quantum coupling effect between the layers in the vertical heterojunction can lead to novel physical properties.The electrical and optical properties of the device can be modulated by adjusting the interface of the heterostructure.At present, with the increasing demand for integration and functionality of electronic devices and optoelectronic devices, two-dimensional heterostructures have attracted more and more attention from researchers.Effective control of two-dimensional heterojunction structures (including interfaces) is a prerequisite for building high performance and high integrated devices.In this paper, the fabrication methods of various kinds of two-dimensional heterojunction are compared, and the structure, working principle and performance of the main two-dimensional heterojunction based electronic and optoelectronic devices are introduced.The challenges of two-dimensional heterojunction in practical application are pointed out.
