WebApr 26, 2024 · The result shows that the H adsorption bond on the heterostructure occupies fewer anti-bond states compared with pristine NDG (Fig. S6 and S7 in supplementary material), which indicates that the bonding strength between H and the heterostructure substrate is higher. In the M_Sc/G_N8 heterostructure, ΔG H∗ H∗ of … WebThe Coulomb excitations of charge density oscillation are calculated for a double-layer heterostructure. Specifically, we consider two-dimensional (2D) layers of silicene and graphene on a substrate. From the obtained surface response function, we calculated the plasmon dispersion relations, which demonstrate how the Coulomb interaction …
