摘要：

We study the injection of single charge carrier in one-dimensional molecular wires in the presence of coherent electron-lattice coupling. We show that charge injection at the molecule/metal interface induces lattice distortions in the molecule itself reflecting the formation of polaron-like defect. The behaviour of the charge density of the injected carrier and the mean position of the carrier depend strongly on the value of the injection energy relative to the band edges of the molecular wires.
