title: High-order tunneling processes in single-porphyrin transistors.
abstract: Cotunneling and the Kondo effect are observed in single-electron transistors incorporating cobalt-porphyrins. These effects are attributed to high-order tunneling and strong coupling between the electrodes and the intervening porphyrin.
