in this study, tio2 and zno nanofilms were prepared by sol-gel spin-coating method. nanofilms were characterized by x-ray diffraction (xrd), energy dispersive analysis of      x-ray (edx), scanning electron microscopy (sem) and field emission scanning electron microscopy (fe-esm). structural and morphological properties of nanofilms were investigated. the average crystalline size of tio2 and zn...

Many applications in a diverse demographic of engineering fields require knowledge of the thickness of thin films and coatings. An example of some applications for which thin film thickness is critical are semiconductors, optics, and protective coatings. There are various methods for measuring thin film thickness, however, many of them are destructive, or are only capable of measuring thickness...

the molecular dynamic technique was used to simulate the nano-indentation test on the thin films of silver, titanium, aluminum and copper which were coated on the silicone substrate. the mechanical properties of the selected thin films were studied in terms of the temperature. the temperature was changed from 193 k to 793 k with an increment of 100 k. to investigate the effect of temperature on...

In recent years, the demand for thin film coatings on large area substrates has been rapidly increasing. Coating is some times required to make an object harder, or to provide the surface with particular electrical and optical properties. Hence, research on thin film science has received much attention due to its tremendous applications in modern technology. The importance of coatings and the s...

In this paper, we reviewed researches about the titanium nitride (TiN) and titanium carbide (TiC) single and multilayer coatings. These coatings were deposited by the plasma assisted chemical vapor deposition (PACVD) technique. Plasma-based technologies are used for the processing of thin films and coatings for different applications such as automobile and aerospace parts, computer disc drives,...

Evaporated optical coatings fabricated from hafnium dioxide and silicon dioxide are the standard approach for high-peak-power laser components due to the high laser damage resistance of such coatings and the ability to deposit on largeaperture substrates. The tensile film stresses of such coatings may lead to failure, however, particularly in low-relative-humidity purged or vacuum use environme...

Recent developments in thin-film coatings for optical communication systems are reviewed. Particular emphasis is given to thin-film designs with dispersion related to the photonic crystal superprism effect. A single dispersive coating may be used for multiplexing or demultiplexing several wavelength channels by spatial beam shifting. 2004 Optical Society of America OCIS codes: (310.0310) Thin ...
