A review on the mechanisms and characterization methods of molecu- lar electronic transport is presented. Using self-assembled monolayers (SAMs) of alkanethiols in a nanometer scale device structure, tunneling is unambiguously demonstrated as the main conduction mechanism for large bandgap SAMs, exhibit- ing well-known temperature and length dependencies. Inelastic electron tunneling spectroscopy exhibits clear vibrational modes of the molecules in the device, pre- senting the ?rst direct evidence of the presence of molecules in a molecular device.
