Abstract The periodic lattice registry of multi-walled carbon nanotubes (MWCNTs)
have been exploited for the possibilities of development of nanodevices. This paper
studied the telescoping behaviors of double-walled carbon nanotubes (DWCNTs)
by atomic-scale finite element and tight-bind Green function methods. It was found
that telescoping a DWCNT (e.g., (6,3)/(12,6)) will induce a rotational motion of the
inner CNT that has a chirl angle θ (0◦ < θ < 30◦). This telescoping-induced rotational motion does not exist for armchair and zigzag DWCNTs due to the symmetry
of CNTs. The rotational angle is completely determined by the chirality of the inner
CNT and… More >
