Abstract

We report thickness-dependent morphologies of a Pd film on n-layer graphenes. ViaRaman spectroscopy-based technique, obvious charge transfer has been observed among Pd and graphenes, which is also dependent on the layer number. With the increase of the layer number, the Pd film becomes coarser, and the electron transfer becomes lower.
