Such lack of local stability is consistent with the absence of experimental evidences of diamond-like structure formation from multilayer Graphene when exposed to pressure in the range of 0.0001-10 GPa in anhydrous solvents. However the presence of chemical groups, such as methoxy, hydrogens or hydroxy groups, may substantially decrease the pressure required to promote covalent bonds between carbon atoms in distinct layers of BLG. In the next section we will investigate the possible interplay between the BLG functionalization and the formation of diamond-like structures by combining DFT-MD simulations with metadynamics. In particular we will explore the possible mechanisms of reactions and the associated free-energy barriers characterizing the BLG/methanol functionalization and BLG's inter-layer reactivity.
