Structure and NLO Properties of Uncork single wall Carbon Nanotubes with Finite length
A series of length-limited carbon nanotube with both end openings(n,0)(n=5--10) were designed by ChemSketch10.0. The electronic structure of title molecules was calculated by using semi-empirical AM1 method. The first, second and third order polarizabilities of the title molecules were calculated by using FF(Finite Field)/AM1 method. The result shows that those with N=3 has better second and third order optical capabilities, which can serve as potential nonlinear optical materials. Moreover, the energy gap between HOMO and LUMO for title molecules was found to surge from odd to even n as the tube diameter increases, and decrease with the increasing of tube length.
