Abstract
We investigate a semiconductor single-electron tunnelling transistor (SET) in the limit of extremely strong coupling to the leads. Several consecutive Fano resonances are observed in transport experiments instead of the regular Coulomb resonances. We quantitatively investigate the lineshapes of the Fano resonances. The observation of Fano resonances in an SET is attributed to the simultaneous presence of a resonant and a continuous conductance channel through the device. We discuss the nature of the second conductance channel.
