Talk no.24 Abstract: Benzene based ring molecules, carbon nanotubes, and hexagonal graphene pieces have been considered as possible components of electromagnetic metamaterials operating in the near infrared or visible-frequency-regime. In all cases the dangling bonds at the edges have been passivated by hydrogen incorporation. Using DFT and LCAO techniques the structure and the stability of the undoped and the doped molecules were studied. The adsorption coefficient of these molecules was calculated under the assumption of almost negligible el – ph scattering. The capacitance component in the SRR-like operation may be incorporated by doping the molecule with a cluster of pentavalent or trivalent atoms such as nitrogen, boron, or iron. Duration: 40 min. |
