Thermally evaporated 50-nm nickel thin films coated on borosilicate glass substrates were nanostructured by excimer laser (0.5 J/cm(2), single shot), DC electric field (up to 2 kV/cm) and trench-template assisted technique. Nanoparticle arrays (anisotropic growth features) have been observed to form in the direction of electric field for DC electric field treatment case and ruptured thin film (...

The review concentrates on the analysis of the RF hydrogen plasma effect on thin-film metal-dioxide-silicon and silicon-dioxide silicon structures which are a modern basis of microand nanoelectronics. The especial attention is paid to athermic mechanisms of transformation of defects in dioxide, SiO2-Si interface and SiO2-Si nanocrystal ones and thin layers of silicon; atomic hydrogen influence ...

Undoped and Sn, Ni-doped nanostructured ZnO thin films were deposited on glass substrates using a successive ionic layer adsorption and reaction (SILAR) method at room temperature. The SILAR deposited zinc oxide films have been rapid photothermal processing (RPP) at various temperatures to study the effect of annealing on the sensing properties. Structural, electrical and sensing properties wer...

Nanostructured light trapping has emerged as a promising route toward improved efficiency in solar cells. We use coupled optical and electrical modeling to guide optimization of such nanostructures. We study thin-film n-i-p a-Si:H devices and demonstrate that nanostructures can be tailored to minimize absorption in the doped a-Si:H, improving carrier collection efficiency. This suggests a metho...

We propose multi-periodic nanostructures yielded by superposition of multiple binary gratings for wide control over photon emission in thin-film devices. We present wavelength- and angle-resolved photoluminescence measurements of multi-periodically nanostructured organic light-emitting layers. The spectral resonances are determined by the periodicities of the individual gratings. By varying com...

mn doped zno nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. mn doped zno nanocomposite thin film was characterized by means of x-ray diffraction (xrd) and scanning electron microscopy (sem). the photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...

Physical vapor deposition under conditions of an obliquely incident flux results in a film formation with an inclined columnar structure. These columns will be oriented toward the vapor source because of the self-shadowing effect, and they are homogenously distributed on the substrate surface because of the limited surface diffusion ability of ad-atoms when there is no additional substrate heat...

Surfactants self-associate into micelles with various radii of curvature, vesicles, and ordered liquid crystalline phases at the concentration above the critical micelle concentration (CMC) [1]. Recent atomic force microscopy (AFM) studies have shown that analogous structural transitions also occur at the solid/liquid interface. At the solid/liquid interface, surfactants selfassemble into discr...

Nanoscale ZnO is one of the best choices for ultraviolet (UV) protection, not only because of its antimicrobial properties but also due to its potential application for UV preservation. However, the behavior of nanostructured thin ZnO films and long-term effects of UV-radiation exposure have not been studied yet. In this study, we investigated the UV-protection ability of sol gel-derived thin Z...

This paper describes the developed complex of vacuum thin-film technologies for creating electrode materials energy storage devices an intelligent source accumulation, and transportation electricity. Thin-film technologies, in contrast to thick-film allow more efficient use surface properties, using nanostructured structures. The allows us implement a promising technology new generation based o...
