Au nanostructures coated with a ultrathin film of Al2O3 - measurements and FDTD simulations

Gold plasmonic platforms have been coated with an ultra-thin films of aluminium oxide. Optical measurements, showing the influence of the thickness of Al2O3 on plasmon resonance position. The observed red-shift of the resonance location with the increase of the thickness of the Al2O3 film, can be explained by the change in the dielectric function of this film. In this repository tResults of measurements of Al2O3 ulra thin films and structures Au/Al2O3.
