Electronic Transport through C60 — •Tobias Böhler, Jochen Grebing, and Elke Scheer — Universität Konstanz
The electronic transport through a single or a few C60 molecules is studied experimentally with the help of the mechanically controllable break-junction (MCB) technique [1]. The tip electrodes of the MCB are fabricated of aluminum or gold. The molecule is evaporated onto an opened break-junction under UHV conditions and at low temperatures. At room and low temperature the experiment shows evidence that the conductance of a single C60 molecule between gold contacts is in the order of 0,1 G0. This can be seen in opening and closing curves as well as in time-dependent fluctuations of the conductance. First results of C60 between Al electrodes are presented.
