Transparent and conductive Al-doped ZnO (AZO) films have been grown with various thicknesses between 0.3 and 1.1 μm by magnetron sputtering at room temperature onto soda lime glass substrates. After deposition, the samples have been annealed at temperatures ranging from 150 to 450 °C in air or vacuum. The optical, electrical, and structural characteristics of the AZO coatings have been analyzed as...
In the present study DLC films deposited from acetylene gas by a closed drift ion source were investigated. Ion beam energy effects on structure as well as optical and electrical properties of the synthesized films were studied. Non-monotonic dependence of structure of the DLC films on ion beam energy was observed. The highest sp 3 /sp 2 ratio as well as highest optical transparency...
Copper indium diselenide (CuInSe 2 ) was prepared by direct reaction of high purity elemental Copper, Indium and Selenium. CuInSe 2 thin films were prepared on well-cleaned glass substrates by a hot wall deposition technique. The X-ray diffraction studies revealed that all the deposited films are poly crystalline in nature, single phase and exhibit chalcopyrite structure. The crystallites...
TiCN coatings were deposited using a large area filtered arc deposition (LAFAD) technique from Ti targets in a mixture of N 2 and CH 4 gases. CH 4 fraction was varied from 0 to 50% to change the C content in the coatings. Scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS), x-ray diffraction (XRD), and substrate bending method were used to characterize...
Titanium oxide thin films were deposited by DC reactive magnetron sputtering on ZnO (80 nm thickness)/soda-lime glass and SiO 2 substrates at different gas pressures. The post annealing on the deposited films was performed at 400 °C in air atmosphere. The results of X-ray diffraction (XRD) showed that the films had anatase phase after annealing at 400 °C. The structure and morphology of deposited...
During low pressure carburizing a carbon layer precipitates on the surface of steel parts. The structure of the carbon layer was tested by means of optical and electron microscopy and Raman spectroscopy as well. It was found out that the carbon layer is composed of fine-crystalline graphite. A sample was carburized (boost step), and was subsequently observed with an optical microscope. The dominant...
