thin film phthalocyanines(pc), incloding zinc, iron, and magnesium phthalocyani-nes, were prepared by vacuum deposition method. chronocoulometry was used to study the charge transfer reaction mechanism of ionic species through the thin films. the results obtained in chronocoulometric studies shows that the thin film phthalocyanines could operate via two mechanisms.the first mechanism metal pc t...

We report the first observation of a transient all electric field induced magnetic anisotropy in a thin film metallic ferromagnet. We generate the anisotropy with a strong (approximately 10(9) V/m) and short (70 fs) E-->-field pulse. This field is large enough to distort the valence charge distribution in the metal, yet its duration is too brief to change the atomic positions. This pure electro...

It is shown that the size effect recently observed by Espinosa et al., fJ. Mech. Phys. Solids 51, 47 s2003dg in pure tension tests on free thin metallic films can be explained by the existence of a boundary layer of fixed thickness, located at the surface of the film that was attached onto the substrate during deposition. The boundary layer is influenced by the epitaxial effects of crystal grow...

Thin metallic films have several potential applications in MEMS field, and one of them is used as infrared absorber. In this paper, we first build a model of metallic infrared absorption and then discuss the transmission characteristics of infrared through metal and dielectric film. For a thin film material, the maximum absorption will occur when its sheet resistance equals to the impedance of ...

Double layer distribution exists in Cu2SnZnSe4 (CZTSe) thin films prepared by selenizing the metallic precursors, which will degrade the back contact of Mo substrate to absorber layer and thus suppressing the performance of solar cell. In this work, the double-layer distribution of CZTSe film is eliminated entirely and the formation of MoSe2 interfacial layer is inhibited successfully. CZTSe fi...

We analytically study second-harmonic (SH) generation from thin metallic films with subwavelength noncentrosymmetric patterns. Because the thickness of the film is much smaller than the SH wavelength, retardation effects are negligible. The far-field SH intensities are thus dominated by an effective electric dipole. It is further demonstrated that internal bulk SH polarization density is compar...

Thin-film solar cells enable a strong reduction of the amount of silicon needed to produce photovoltaic panels but their efficiency lowers. Placing metallic or dielectric nanoparticles over the silicon substrate increases the light trapping into the panel thanks to the plasmonic scattering from nanoparticles at the surface of the cell. The goal of this paper is to optimize the geometry of a thi...

Using the Ginzburg–Landau–Devonshire theory and taking into account structural difference between imperfect surface layer and bulk ferroelectrics, the behavior of ferroelectric thin film coated with two metallic electrodes is studied. The effects of the imperfect surface layer are to reduce effective polarization, produce non-uniform polarization distribution and lower the phase transition temp...

In this study, the hopping conduction distance and bipolar switching properties of the Gd:SiOx thin film by (radio frequency, rf) rf sputtering technology for applications in RRAM devices were calculated and investigated. To discuss and verify the electrical switching mechanism in various different constant compliance currents, the typical current versus applied voltage (I-V) characteristics of...

This paper presents the investigation of a novel concept involving the combination of piezoelectric and new thin-film battery technology to form multifunctional self-charging, load-bearing energy harvesting devices. The proposed self-charging structures contain both power generation and energy storage capabilities in a multilayered, composite platform consisting of active piezoceramic layers fo...
