【摘要】：二維材料異質(zhì)結(jié)是由石墨烯、六方氮化硼、過渡金屬二硫族化合物、黑磷等二維材料通過面內(nèi)拼接或?qū)娱g堆疊形成的,并由此可分為二維材料面內(nèi)異質(zhì)結(jié)和垂直異質(zhì)結(jié).二維材料面內(nèi)異質(zhì)結(jié)可以實(shí)現(xiàn)區(qū)域內(nèi)載流子的特殊傳輸行為;而垂直異質(zhì)結(jié)中的層間量子耦合效應(yīng)能夠?qū)е滦路f的物理特性,通過調(diào)節(jié)異質(zhì)結(jié)構(gòu)界面可調(diào)制器件的電學(xué)及光學(xué)性能.目前,隨著電子器件、光電器件等對(duì)集成性、功能性的要求不斷提高,二維材料異質(zhì)結(jié)越來越多地受到研究者的關(guān)注,實(shí)現(xiàn)二維材料異質(zhì)結(jié)結(jié)構(gòu)(包括界面)的有效調(diào)控是構(gòu)筑高性能、高集成器件的前提.本文主要對(duì)比各類二維材料異質(zhì)結(jié)的制備方法,介紹主流的幾類二維材料異質(zhì)結(jié)基電子器件和光電器件的結(jié)構(gòu)、工作原理和性能,展望有前景的新型制備方法,并指出二維材料異質(zhì)結(jié)在實(shí)際應(yīng)用中面臨的挑戰(zhàn).
[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.
