Abstract
Structural and electronic properties of nLi and nLi+ (n=1-3) doped mono-vacancy defected carbon nanocapsule (CNC) systems have been investigated theoretically by performing semi-empirical self-consistent-field (SCF) molecular orbital (MO) and density functional theory (DFT) methods. Semi-empirical SCF MO method at PM3 level has been considered to optimize fully the geometry of the CNCs in their ground states. The total energies of these structures were calculated using B3LYP exchange-correlation functional in DFT method with 6-31G basis set. The studied systems include nLi/nLi+ doped (5,5) and (9,0) single-walled CNCs with mono-atom vacancies. The molecular properties, energies, some selected MO eigenvalues and dipole moments of the studied capsules have been reported. Furthermore, molecular dynamics simulations have been performed to study the structural properties and energetics of nLi/nLi+ doped mono-vacancy defected CNCs.
