RT Journal Article T1 Second layer of H2 and D2 adsorbed on graphene A1 Gordillo, M.C. A1 Boronat, Jordi K1 Graphene K1 Monte Carlo calculations AB We report diffusion Monte Carlo calculations on the phase diagrams of para-H2 and ortho-D2 adsorbed on top of a first layer of the same substances on graphene. We found that the ground state of the second layer is a triangular incommensurate solid for both isotopes. The densities for promotion to a second layer and for the onset of a two-dimensional solid on that second layer compare favorably with available experimental data in both cases.
