Since the 1960s, Graphite intercalation compounds (GIC) have been extensively studied, showing many new properties and exotic physics. This inspired many to investigate a single or few-layer intercalated graphene. Intercalated graphene has many extraordinary properties and it is different compared to pristine graphene or bulk GICs, with great spectra of characteristics induced by various intercalants. This method opens new possibilities for research and applications in electronics and photonics. Here we present the results of a DFT study on electronic and vibrational properties of the graphene doped with Sr and Yb adatoms, taking into account that only their corresponding bulk compounds have been investigated so far. The calculations were performed in Quantum Espresso software package.
