In this paper, we proposed the effects of Mo thickness on the properties of AZO/Mo/AZO multilayer thin films for opto-electronics applications. The structural, optical and electrical properties of AZO/Mo/AZO thin films were investigated. Optimization of the thin films coatings resulted with low resistivity of 9.98 × 10 Ω-cm, mobility of 12.75 cm/V-s, carrier concentration of 1.05 × 10 cm, maxim...

We report a layer-by-layer approach to the fabrication of thin polymer-based multilayers that release DNA rapidly in physiologically relevant environments. This approach exploits the properties of a weak anionic polyelectrolyte [poly(acrylic acid); PAA] to disrupt ionic interactions and promote disassembly in coatings that otherwise erode slowly. We investigated this approach using multilayers ...

Protective ultra-thin barrier films gather increasing economic interest for controlling permeation and diffusion from the biological surrounding in implanted sensor and electronic devices in future medicine. Thus, the aim of this work was a benchmarking OPEN ACCESS Coatings 2013, 3 269 of the mechanical oxygen permeation barrier, cytocompatibility, and microbiological properties of inorganic ~2...

Titanium oxide (TiO2) thin films were deposited by RF magnetron sputtering on Si and glass substrates. The microstructure, surface morphology, and optical properties of the thin films were investigated by grazing incidence X-ray diffraction (GIXD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), and UV/VIS spectrophoto...

Coatings of poly(2-vinylpyridine) have been formed on mild steel substrates in aqueous medium by electrochemical polymerization of the 2-vinylpyridine monomer. The pH of the solution has been found to be critical for this electropolymerization coating process. At low pH (below 3.5), even with an efficient initiation reaction, the propagation process was impeded and no substantial polymer film w...

The transition metal nitrides like titanium nitride exhibit very interesting color variation properties depending on the different plasma deposition conditions using cylindrical magnetron sputtering method. It is found in this deposition study that nitrogen partial pressure in the reactive gas discharge environment plays a significant role on the color variation of the film coatings on bell-met...
