Modulation of the Second Order Nonlinear Optical Properties of Helical Graphene Nanoribbons Through Introducing Azulene Defects or/and BN Units
The current study has obtained excellent potential nonlinear optical(NLO) materials by combining density functional theory methods with sum-over-states model to predict the second order NLO properties of helic...

Theoretical Studies on the Electronic Structure of Nano-graphenes for Applications in Nonlinear Optics
In this work, azulene is introduced into nano-graphene with coronene center to enhance the second-order nonlinear optical (NLO) properties. The sum-over-states(SOS) model based calculations demonstrate that dip.....

Structures, stabilities, aromaticity, and electronic properties of C66 fullerene isomers, anions (C66 2−, C66 4−, C66 6−), and metallofullerenes (Sc2@C66)
Among all the 4478 classical isomers of C66, C66(C s :0060) with the lowest number of pentagon–pentagon fusions was predicted to be the most stable isome...

Theoretical explorations on the armchair BN nanotube with defects
A systematic study of armchair boron nitride nanotubes (BNNTs) with defects has been carried out within density functional theory. The effect brought by the defects is localized. The defect sites have major co...
