High-resolution TEM micrograph of (a) empty SWNT bundles and (b) -filled SWNT bundles.
Nanotube bundles are actuated by applying an ac signal between the sample and ground electrode. Many SWNT bundles are hung out from the torn edge of the buckypaper.
X-ray-diffraction patterns from the empty buckypaper sample (I) and from the peapod buckypaper sample (II).
Typical selective area diffraction (SAD) pattern of an isolated bundle. Several broken streaks appear perpendicular to the bundle axis. The reciprocal lattice spacing is measured to be , corresponding to a lattice periodicity of 9.97 Å.
Dependence of the bending modulus on the bundle diameter .
Length , diameter , detected resonant frequency , and corresponding of empty and filled SWNTs bundles studied in this work.
