Abstract
Abstract Using molecular dynamics simulations, we investigate the movement behavior of double-walled carbon nanotube containing single atom vacancy defect and Stone–Wales defect. The carbon nanotube thermal actuator consists of a short outer tube and a long inner tube driven under temperature gradient. It is found that the presence of these defects introduces resistance of the nanotube systems, which affects their amplitude and speed. The oscillation motion of the outer nanotube is found possible to be produced, which can be achieved by devising proper initial position of the outer tube, the defect type and the temperature gradient. Our results demonstrate the effect of defects on the motion of carbon nanotubes and show that it is possible to control and tune the motion behavior of nanotubes through the introduction of defects.

Summary
Due to their remarkable stiffness, strength,elasticity and extremely low interlayer friction, carbon nanotubes (CNTs) have attracted great attention in engineering applications. Their excellent wear resistance quality and limited movement ability (rotation or translation) make them key components of various applications in the field of nanotechnology.There are many new nano-devices based on double-. The movement characteristics and the instability of CNT containing a long outer tube and a short inner tube have been studied extensively [10, 16]. The oscillatory characteristics of the oscillators containing sp3hybridized Stone-Wales defects is studied by Guo et al [19], and their results show that it is possible to control the motion of the inner nanotube by introducing sp3-hybridized defects on the outer nanotube.
