Abstract: (22 Views)
Using quantum computational calculations, the electronic and optical properties of monolayer nanostructures of copper, silver, and gold compounds were investigated. The results of recent studies revealed that these compounds are stable in a centrosymmetric hexagonal phase and possess a completely planar structure. These materials exhibit metallic characteristics, such that the s and d orbitals contribute metallic states at the Fermi level. Optical calculations further demonstrate that intraband transitions play a dominant role up to energies of about 3 eV. The plasmonic frequency of these compounds appears around 4 eV. Moreover, quantum capacitance calculations indicate their remarkable capability for energy storage; specifically, within the potential window of aqueous systems, the charge storage density for the copper monolayer was obtained to be significant. The findings suggest that copper, silver, and gold monolayers hold great potential for applications in plasmonic resonance sensors as well as promising platforms for energy storage.
