An investigation was made of the effects of vacancy defects upon the pull-in behavior of carbon nanotubes. The influence of single, double and triple vacancies in various peripheral and longitudinal positions was studied. The results revealed that the vacancy defects drastically reduced the pull-in charge because they weakened the nanostructure. The effects of residual stresses upon the pull-in and vibrational properties of the carbon nanotubes were studied. The influence of angular deviations from the parallel positions of the nanotube and ground plate during fabrication were also reported.
