Abstract
The invention relates to a method for forming a telescoped multiwall nanotube. Such a telescoped multiwall nanotube may find use as a linear or rotational bearing in microelectromechanical systems or may find use as a constant force nanospring. In the method of the invention, a multiwall nanotube is affixed to a solid, conducting substrate at one end. The tip of the free end of the multiwall nanotube is then removed, revealing the intact end of the inner wall. A nanomanipulator is then attached to the intact end, and the intact, core segments of the multiwall nanotube are partially extracted, thereby telescoping out a segment of nanotube.
Claims15
A device comprising a telescoped multiwall nanotube comprised of:
- (a) an outer shell having a cylindrical wall, a closed end, and an interior cavity defined by the cylindrical wall and the closed end;
- and
- (b) a telescoped segment partially housed within the interior cavity of the outer shell and partially extending from the outermost shell, wherein said telescoped segment has a cylindrical segment wall, a closed segment end, and a segment cavity.
