Stone-Wales transformations triggered by intrinsic localized modes in carbon nanotubes

Abstract: The crucial role of intrinsic localized modes ͑ILMs͒ in the atomic scale as a trigger of defect nucleation was studied using molecular-dynamics simulations for a ͑5,5͒ armchair carbon nanotube ͑CNT͒ under axial tension. A localized vibration at a pair of neighboring atoms was found to be the ILM, which simultaneously produces an intense concentration of kinetic energy, even in the structurally homogeneous CNT. The excited ILM was gradually amplified by the nonlinearity of C-C interaction. The amplified ILM, th… Show more

“…It has been shown that graphene and graphane support DBs [33][34][35][36][37] . The first theoretical studies on DBs in graphene and carbon nanotubes have been done by Japanese researchers [38][39][40][41][42][43] . In their studies the DBs with frequencies above the phonon spectrum were identified.…”

“…В работах [6,[8][9][10][12][13][14][15][18][19][20][21][22][23][24][25] ставилась задача ис-следования свойств ДБ при использовании реалистич-ных межатомных потенциалов. Были изучены двухком-понентные кристаллы с потенциалами Морзе с учетом дальнодействующих взаимодействий [8,21,22], с ион-но-ковалентной связью [6,9,25], а также углеродные нанотрубки и графен [12][13][14][15].…”

Полученные результаты свидетельствуют о мягком типе нелинейности во всех исследованных кристаллах.…”
