Abstract

We study electron transport across a carbon molecular junction consisting of a C60 molecule sandwiched between two semi-infinite metallic carbon nanotubes. It is shown that the Landauer conductance of this carbon hybrid system can be tuned within orders of magnitude not only by varying the tube-C60 distance, but more importantly at fixed distances by (i) changing the orientation of the ...
