摘要：

The differential conductance in a suspended few layered graphene sample is found to exhibit a series of quasiperiodic sharp dips as a function of bias at low temperature. We show that they can be understood within a simple model of dynamical Coulomb blockade where energy exchanges take place between the charge carriers transmitted through the sample and a dissipative electromagnetic environment with a resonant phonon mode strongly coupled to the electrons.
