We present theoretical calculations of the Casimir force for Au thin films near the insulator-conductor transition that has been observed experimentally. The dielectric function of the Au thin films is described by the Drude-Smith model. The parameters needed to model the dielectric function such as the relaxation time, plasma frequency and the backscattering constant depend on the thickness of...

A polymer film draping over a point of contact will wrinkle due to the strain imposed by the underlying substrate. The wrinkle wavelength is dictated by a balance of material properties and geometry; most directly the thickness of the draping film. At a critical strain, the stress in the film will localize, causing hundreds of wrinkles to collapse into several discrete folds. In this Letter, we...

In this study, the influence of post deposition annealing steps (PDA) on the electrical resistivity of evaporated titanium/platinum thin films on thermally oxidised silicon is investigated. Varying parameters are the impact of thermal loading with maximum temperatures up to TPDA=700 °C and the platinum top layer thickness ranging from 24 nm to 105 nm. The titanium based adhesive film thickness ...

The Mn K edge X-ray absorption near edge structure (XANES) of Pr0.67Sr0.33MnO3 films with different thicknesses on (001) LaAlO3 substrate was measured, and the effects of strain relaxation on film properties were investigated. The films showed in-plane compressive and out-of-plane tensile strains. Strain relaxation occurred with increasing film thickness, affecting both lattice constant and MnO...

We theoretically and experimentally demonstrated that the resonant wavelength of long period fiber gratings (LPG) could be shifted in a large magnitude by coating only nm-thick thin-film whose refractive index is higher than that of the glass cladding. The resonant wavelength shift results from either the variation of the thickness of the film and/or the variation of the refractive index of the...

Understanding how surface physicochemical properties influence the settlement and adhesion of marine fouling organisms is important for the development of effective and environmentally benign marine antifouling coatings. We demonstrate that the thickness of random poly(HEMA-co-PEG10MA) copolymer brushes affect antifouling behavior. Films of thicknesses ranging from 50 to 1000 Å were prepared vi...

Monoshaped and monosized copper nanostructured particles have been prepared by potentiostatic electrochemical deposition on an ultrathin polypyrrole (PPY) film, electrochemically grown on a Si(100) substrate sputter-coated with a thin gold film or gold-film electrode (GFE). The crystal size and the number density of the copper nanocrystals have been examined by varying several deposition parame...

This work applies the molecular dynamics simulation method to study a Lennard-Jones liquid thin film suspended in the vapor and to explore the film thickness effect on its stability. For the accurate estimation of local pressure distributions in the film, an improved method is proposed and used. Simulation results indicate that profiles of the local surface tension distribution vary widely with...

Submitted for the MAR10 Meeting of The American Physical Society Draping Films: A Wrinkle to Fold Transition DOUGLAS HOLMES, Princeton University, ALFRED J. CROSBY, Universtity of Massachusetts Amherst — This work focuses on the wrinkle-to-fold transition in glassy and elastomeric thin films. In biological systems, the process of folding is critical to morphogenesis, defining such features as t...

217 Abstract—As silicon devices shrink and their density increases, the low dielectric constant materials instead of SiO 2 film is required. SiOC film as low-k films was deposited by the capacitively coupled plasma chemical vapor deposition and then annealed at 300~500 ℃ to find out the properties of the dependence on the temperature and polarity. This study researched the dielectric constant u...
