Carbon nanotubes (CNTs) have attracted considerable attention due to their unique structure, remarkable properties, and their potential for a variety of applications, since their discovery by Iijima in 1991.The nanotube's high field enhancement, high aspect ratios, small tip radii of curvature and high current density make it a nearly ideal electron source for field emission. This paper discusses...
We, along with others, have developed several chemical vapor deposition (CVD) methods for large-scale production of vertically-aligned single-walled, multiwalled, and super-long carbon nanotube arrays. The resultant aligned carbon nanotube arrays can be transferred onto various substrates of particular interest in either a patterned or non-patterned fashion. The well-aligned structure provides additional...
This paper reports on an evaluation of the adhesion force between silicon and carbon nanotubes (CNTs), which were directly synthesized on a silicon substrate by chemical vapor deposition (CVD). CNTs bridging between silicon tips were pushed with a force-sensing cantilever to break the adhesion between silicon and CNTs. We measured the force acting on the cantilever at the moment of breaking the adhesion...
Carbon nanotubes (CNTs) have been proposed for applications in microelectronic applications, especially for electrical interconnects and nanodevices, due to their excellent electrical, thermal and mechanical properties. Usually, the CNTs produced by arcing, laser ablation or chemical vapor deposition (CVD) are inevitably close-ended. Due to the weak coupling of the individual walls and close ends,...
