The transmission spectrum of single-molecule junctions provides fingerprint information on the charge-transport properties. A technique called single-molecule photoelectron tunnelling spectroscopy has been developed that enables mapping of the transmission spectrum beyond the highest occupied molecular orbital (HOMO)–lowest unoccupied molecular orbital (LUMO) gap at room temperature and can be used to explore the energy-dependent charge transport through single-molecule junctions.
