Upon the discovery of the superatom states in endohedral metallofullerenes(EMFs), the superatom properties have become attractive, because ultrafastmotion of the trapped atom modifies the charge distribution in the fullerenecage. However, the observation of ultrafast atom motion in the fullerene cageis very challenging, since dynamical processes take place in the terahertz(THz) frequency range in a picometer region. Here, we report on the THzspectroscopy of single Ce@C82 EMF molecules by using the single moleculetransistor geometry. Due to the vibron-assisted tunneling process, two broadphotocurrent peaks are observed in the THz spectra and are ascribed to thebending and stretching motions of the encapsulated single Ce atom. This workdemonstrates that THz spectroscopy using nanogap electrodes can detect a motionof a single atom, opening a door to ultrafast THz nanoscience on thepicometer-scale.
