Abstract

In this work, we investigate the interaction of silver with micromechanical exfoliated bilayer graphene (BLG) using Raman spectroscopy. We evaluate the behavior of the most characteristic Raman BLG bands as a function of the laser energy. The Ag presence on BLG leads to the appearance of the D band, and the behavior of the 2D and G bands shows that the presence of the silver leads to graphene doping.
