Abstract:
We estimate the stiffness of single-walled carbon nanotubes by
observing their free-standing room temperature vibrations in a
transmission electron microscope. The nanotube dimensions and
vibration amplitude are measured from electron micrographs, and it is
assumed that the vibration modes are driven stochastically and are
those of a clamped cantilever.
Micrographs of 27 nanotubes in the diameter range 1.0 to 1.5 nm were
measured to yield an average Young's modulus of
