Abstract
Inelastic electron tunneling spectroscopy of Ce(2)@C(80) dimetallofullerenes reveals a low-energy inelastic excitation that is interpreted using ab initio calculations and associated with the movements of encapsulated Ce atoms inside the C(80) cage. The electron-vibration interaction in Ce(2)@C(80) is unusually high, inducing a pronounced zero-bias anomaly in differential conductance of Ce(2)@C(80).
Our observations show that the atoms encapsulated in fullerene cages can actively participate in determining the properties of molecular junctions.
