DFT explain that negative lattice mismatch of deposited layer (Graphite) is smaller than that of the substrate (Cu(111)), causing the deposited layer to stretch and accommodate the larger lattice of the substrate. Conversely, the substrate might compress slightly if the deposited film imposes a significant strain

Figure: Optimized configurations of Lithium polysulfides on the surfaces of (a) CN and (b) the heterostructure of CNCNT. The yellow, pink, cyan, and blue spheres represent sulfur (S), lithium (Li), carbon (C), and nitrogen (N) atoms, respectively. Panel (c) displays the binding energies and panel (d) illustrates the relative free energy for the discharging process from S8 to Li2S on both CN and CNCNT surfaces.
