Characteristics of the Sculptured Cu Thin Films and Their Optical Properties as a function of deposition rate

Sculptured copper thin films were deposited on glass substrates, using different deposition rates. The nano-structure and morphology of the films were obtained, using X-ray diffraction (XRD), atomic force microscopy (AFM) and scanning electron microscopy (SEM). Their optical properties were measured by spectrophotometry in the spectral range of 340-850 nm. The Scot package was used for modeling the film structure and fitting the calculated optical transmittance results to the experimental data and obtaining, both real and imaginary refractive indices, film thickness and fraction of metal inclusion in the film structure.

Optical Spectra of Graded Nanostructured TiO2 Chiral Thin Films

The rigorous coupled wave analysis method (RCWA) is applied to the graded chiral TiO2 thin films in axial and non-axial excited states using the Bruggeman homogenization formalism. The dependence of the filtering frequency and polarization selectivity as a function of different structural parameters, are investigated. A good agreement with experimental results reported by other researchers is achieved.
