We report the deposition of Ti and TiN films on Si/SiO2 (100) substrate using e-beam evaporation technique. The influence of substrate temperature on the structural and morphological properties has been studied. The structure and morphology of the deposited films were analyzed by X-ray...

During oxy-coal combustion process, limestone desulfurization may change from indirect into direct sulfation due to the high partial pressure of CO2. When the wet flue gas is recycled, the water vapor will also be enriched in the furnace and affect the desulfurization reactions. In the paper,...

Hydrogenated amorphous and nanocrystalline silicon thin films were grown on porous anodic alumina substrates using electron cyclotron resonance-chemical vapor deposition technique from argon, hydrogen and silane gas composition. The structural characterization of the deposited hydrogenated...

In this study, indium tin oxide (ITO) thin films were preparedon glass substrate by electron beam evaporation technique and then were annealed in air atmosphere at 350 °C for 30 min. Increasing substrate temperature (Ts) from 25 to 380°°C reduced sheet resistance of ITO thin films from...

Mechanical alloying process was introduced to produce nanocrystalline TiNi alloy. X-ray diffraction (XRD) analysis showed that, after 8 h of milling, the starting mixture of elements was decomposed into an amorphous phase. XRD confirmed formation of CsCl-type structure after annealing at...

The destabilizing effect of (X) group IV elements (C, Si, Sn and Ge) on NaH + Al was investigated. A significant decrease in the desorption temperature as well as the reaction enthalpy of NaH was achieved with additions of C, Si, Ge and Sn due to the formation of NaAlGe and NaAlSi ternary and...

A new perovskite like system [NH3-(CH2)10-NH3] ZnCl4, has been synthesized and characterized by single crystal X-ray diffraction, thermal analysis and infrared spectroscopic study. This compound crystallize in a triclinic space group P-1, with the unit cell parameters a=7.294(1), b=10.058(9) Å,...

Many environmental parameters affect the production of photovoltaic (PV) systems and dust could be one of the main reasons of degradation of PV panels. PV systems utilized in large and small scales accumulate different types of dust which reduce the efficiency. The dust contents, which represent...

The phase transitions of [N(C3H7)4]2Cd2Cl6 have been evidenced by differential scanning calorimetry (DSC), and the different phases have been studied by Raman scattering on single crystals, in the frequency range 50–3900 cm−1 for temperatures ranging between 294 and 451 K. On heating, two...

Laser ablation has attracted special interest for the growth of thin films. It allows the formation of high quality layers and maintain stoichiometry in the films of even very complex elemental materials. In this work, high quality AgInSe2 (AIS) films were grown onto Si(100) substrates kept at...
