摘要
石墨烯由于具有易于调控的电子结构、稳定的化学性能以及超高的载流子迁移率等特性,其在电子器件领域具有广阔的应用前景。然而,石墨烯为零带隙的半金属材料,开关比较小,其在微纳电子器件中的应用因此被限制。因此,打开石墨烯带隙使其具有明显的开关比,同时保持较高的载流子迁移率是石墨烯广泛应用于电子器件领域的重大挑战。研究者们通过化学掺杂、有机分子接枝、物理吸附等方法对石墨烯的带隙进行调控。本文主要以是否破坏石墨烯的晶格结构或化学结构为分类依据,综述了石墨烯带隙打开方法的最新研究进展。
Graphene has broad application prospects in the field of electronic devices due to its easy-to-control elec-tronic structure,stable chemical properties and ultra-high carrier mobility.However,graphene is a semimetal ma-terial with zero band gap,and the switch is relatively small,which limits its application in microelectronic devices.Therefore,it is a vital step to open the graphene band gap and endow it with a significant switching ratio and main-tain a high carrier mobility,in order to realize the wide application of graphene in the field of electronic devices.In order to open the band gap of graphene,researchers regulated the band gap of graphene by chemical doping,organ-ic molecular grafting and physical adsorption.This paper mainly introduced the latest research progress of graphene band gap opening methods based on whether the lattice structure or chemical structure of graphene is destroyed.
