With silicon-based devices fabrication approaching their physical limits, the carbon nanotubes (CNTs) are emerging materials as high-performance building blocks for micro/nano electromechanical system (M/NEMS) devices. Moreover, the CNTs show significant promise in various frontier fields owing to their unique quasi-one-dimensional structure with central hollow core and nanometer size, and especially their exceptional mechanical, electrical and functional properties. Despite well-marked achievements and att...
