Abstract:Estudo tEórico dE propriEdadEs ópticas não-linEarEs dE nanotubos dE carbono dERecebido em 29/1/08; aceito em 10/9/08; publicado na web em 2/2/09 THEORETICAL ANALYSIS OF NON-LINEAR OPTICAL PROPERTIES FOR CHEMICALLY MODIFIED SINGLE WALL CARBON NANOTUBES. Structure and first hyperpolarizability for a series of armchair a(5,5) chemically modified carbon nanotubes (CNT) were calculated at semiempirical and density functional levels of theory. The 4,4´-substituted stilbenes were selected as chromophore with substitu… Show more
Through DFT calculations and the finite field approach, it is possible to identify some structural and electronic aspects that could lead to enhancement of the nonlinear optical (NLO) molecular properties of graphene oxide and its derivatives.
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.
