Phonon-affected steady-state transport through molecular quantum dots

Original language description

We consider the transport through a vibrating molecular quantum dot contacted to macroscopic leads acting as charge reservoirs. In the equilibrium and nonequilibrium regimes,we study the formation of a polaron-like transient state at the quantum dot forall the ratios of the dot?lead coupling to the energy of the local phonon mode. We show that the polaronic renormalization of the dot?lead coupling is a possible mechanism for negative differential conductance. Moreover, the effective dot level follows one of the lead chemical potentials to enhance resonant transport, causing novel features in the inelastic tunneling signal. In the linear response regime, we investigate the impact of the electron?phonon interaction on the thermoelectrical properties ofthe quantum dot device.
