【摘要】 近年来,一种新型的准一维石墨烯基材料即石墨烯纳米带(graphene nanoribbons,GNRs)受到广泛关注,限域的宽度和丰富的边缘构型使其具有许多不同于二维结构大面积石墨烯的性质和应用。本文介绍了GNRs特殊的边缘效应以及由此产生的电学、磁学等特殊性质,在此基础上进一步介绍了GNRs典型的制备方法、缺陷种类、掺杂和化学改性等,并对功能化的GNRs的应用进行了展望。更多还原

【Abstract】 In recent years,an interesting class of quasi one dimensional graphene-based material,known as graphene nanoribbons(GNRs),has attracted tremendous attention.Owing to the finite width and abundant edge geometries,GNRs present a lot of promising properties and applications,which are quite different from large-area graphene.In this paper we attempt to give an overview of their novel edge effect and the resulting electronic property,magnetic property,etc.We further present some typical preparation methods,defects types,doping,chemical modification and so on.We also provide an outlook of the applications of functional GNRs.更多还原
