\label{sec:microscopic_formation_mechanism_of_nanotube_peapods}


Using molecular dynamics calculations, we have investigated the
absorption of a C\textsubscript{60} molecule in a (10, 10) nanotube either
through the open and or a large defect in the tube wall as possible
scenarios for the hierarchical self-assembly of
(C\textsubscript{60})\textsubscript{\emph{n}}@(10,10 ,,nano-peapods". We found the
absorption through a defect to be significantly more efficient than
the end-on absorption. This process occurs most likely within a narrow
launch velocity range for the fullerene that agrees well with the
observed optimum temperature window for peapod formation.
