Взаимодействие углеродных нанотрубок (7,7) и (8,8) с внедренными атомами

Abstract

Приводятся результаты неэмпирических расчетов по теории функционала электронной плотности углеродных нанотрубок, содержащих атомы лития, натрия, магния, алюминия, кремния и хлора. Путем оптимизации геометрии в базисе 6-31G определены устойчивые положения внедренных атомов, их влияние на ширину энергетической щели мезду занятыми и свободными орбиталями и распределение электронной плотности в системе. The paper presents the results of ab initio modeling of carbon nanotubes «armchair» (7,7) and (8,8) containing atoms of lithium, sodium, magnesium, aluminum, silicon and chlorine with the density functional theory using the code Firefly. We have made calculations of the stable positions of interstitial atoms, their influence on the energy gap between the occupied and unoccupied orbitals and electron density distribution in the systems.
