Space-filling representations of the C/Cu (110) surface with coverages (a) 0.25 and (b) 1.00 ML. The calculated work functions for C/Cu at 0.25 and 1.00 ML coverages were 4.90 eV and 4.89 eV, respectively. Gold and gray spheres represent the Cu and C atoms, respectively. These structures were made using VESTA²⁵.
