  Single-parameter adiabatic charge pumping, induced by a nearby
radio-frequency antenna, is achieved in suspended carbon nanotubes close to the
mechanical resonance. The charge pumping is due to an important dynamic
adjustment of the oscillating motion to the antenna signal and it is different
from the mechanism active in the two-parameter pumping. Finally, the second
harmonic oscillator response shows an interesting relationship with the first
harmonic that should be experimentally observed.
