“…8 the method is examined for three chiral vectors, namely (6,5), (8,1) and (7,5). It can roughly be seen that, the 3 rd neighbor π-TB approach yields a better agreement with the four orbital TB than the nearest neighbor π-TB.…”

“…After its exploration in 1991 by Iijima [1], extensive practical and theoretical researches about its nature gradually began to develop [2][3][4][5][6]. Today, we know about CNTs much more about its chemical, mechanical, optical and electrical properties than before.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
