The first scanning tunneling spectroscopy of graphene flakes equipped with a "gate" electrode has found an unexpected gap-like feature in the energy spectrum of electrons tunneling into graphene's single layer of atoms. Scientists who performed the research believe the peculiar feature arises from the interaction of the tunneling electrons with phonons, the quantized vibrations of the 2-D graphene crystal.
