Transport properties of carbon nanotubes encapsulating C60 and related materials -: art. no. 115413

We have investigated the transport properties of various periodic and nonperiodic C-60@(10,10) peapod systems by varying the distribution of C(60)s encapsulated in the (10,10) nanotube, based on Green function approach within the realistic tight-binding model. The transport properties of the C-60@(10,10) systems strongly depend on the distribution of the C(60)s encapsulated in the (10,10) nanotube. The periodic systems exhibit the quantized transmissions reflecting their band structure. The transmission of the system with a C-120 molecule in an infinite array of C(60)s has dip structures around the energy levels of the C-120 molecule, the half widths of which are dependent on the strength of the interaction between the nanotube and the impurity C-120 molecule.
