In this study, thin films of mesoporous silica with vertically oriented and hexagonally ordered pores have been synthetized investigated. A variety alkyl-imidazolium ionic liquids used as the template, aim to understand how changing chain length on imidazolium cation from hexadecyl (C16) dodecyl (C12) or protic character head affects film formation order pores. addition, different types metal s...

Tungsten oxide (WOx) thin film, which is well known as an electrochromic display, was deposited on the ITO film coated flexible substrates using the RF magnetron sputtering method. Phenomena of processing plasmas, the film quality and the electrochromic properties of deposited WO3 thin film have been studied as parameters of a gas pressure and gas mixture. Experimental results suggest that depo...

Single layers of ZnxCd1-xSe with three different compositions (x = 0.39, 0.59, 0.8) and thickness of 400 nm have been prepared by thermal vacuum evaporation, through alloying of ultra thin ZnSe and CdSe films. The microstructure and surface morphology of ZnxCd1-xSe has been investigated by Atomic Force Microscopy. Chiral and achiral bi-stable smectic C liquid crystal textures were obtained usin...

Using the Langmuir probe method, the reactive plasma parameters were studied in different ratios of oxygen and nitrogen concentrations in a DC cylindrical discharge device.The plasma parameters such as plasma potential, electron density and electron temperature wereextracted from the current-voltage characteristic’s curve of Langmuir probe to find the optimum conditions for deposit the oxy...

In this work, we report a physical deposition based, compact (cp) layer synthesis for planar heterojunction perovskite solar cells. Typical solution-based synthesis of cp layer for perovskite solar cells involves low-quality of thin films, high-temperature annealing, non-flexible devices, limitation of large-scale production and that the effects of the cp layer on carrier transport have not bee...

Interest in to the energy saving technology of by adopting low emissive glass for conventional building has been rapidly increasing [1]. Low emissivity (Low-e) glass has been widely used to increase the energy efficiency of windows. Low-e glass has advantages, such as a high transmittance of about 80% or more in the visible range and a low emissivity in the infrared (IR) range [2]. Recently, OM...
