Copper Telluride (CuTe) thin films have been successfully deposited on a glass substrate Fluorine Tin oxide (FTO) by electrodeposition technique. The absorbance was measured using M501 UV-visible spectrophotometer in the wavelength range of 200-900nm. Copper Telluride (CuTe) thin films were investigated at room temperature. Optical absorption study showed that CuTe films were of indirect band g...

Nanocrystalline tin dioxide (SnO2) thin films were prepared on glass substrate by pulse laser deposition for the first time. The thin films were characterized for their composition, morphology, and crystalline structure by x-ray diffraction, transmission electron microscopy, and high-resolution transmission electron microscopy. It was found that the thin films consisted only of the tetragonal p...

Tin oxide thin film deposited on to glass substrates by the process of DC reactive magnetron sputtering has been used in our work. These films were characterized for their thermoelectric behavior. Further, a novel method has been developed to enhance the Seebeck coefficient of these films. Prior to the oxide film deposition on the glass substrate, thin metal films have been deposited at the two...

This paper presents the optimization process in sol-gel technique to synthesize Titanium dioxide (TiO2) thin films using in-house Nano-TiO2 powder. Nano-TiO2 powder was previously synthesized in our lab from ilmenite which is a tin mining byproduct using a modified hydrothermal method. By varying the mass of Nano-TiO2 powder and acetic acid (catalyst) concentration in the sol-gel process, highl...

The chemical bath deposition (CBD) technique was used for the synthesis of the tin oxide (SnO2) thin films. X-ray diffraction (XRD) was employed to find the crystallite size by using Debye Scherrer’s formula. The surface morphology of SnO2 films was analyzed by the scanning electron microscopic (SEM) studies. The FT-IR spectrum exhibits the strong presence of SnO2. The optical properties of the...

Tin oxide nanostructures, un-doped and Zn-doped, have been prepared by conventional sol-gel technique. Research grade tin chloride (SnCl2.2H2O) and zinc acetate (Zn(O2C2H3)2) were used as tin and zinc sources. Ethylene glycol and alcohol were used as solvents under different synthesis conditions. Transparent un-doped and Zn-doped SnO2 sol was prepared after continuous stirring and refluxing at ...

ITO thin films were deposited by spin coating method starting from indium and tin propoxide in the frame of a sol-gel process. Films with the thickness corresponding to 68 nm for one layer deposition were produced and characterized by X-ray diffraction, transmission electron microscopy and infrared reflection spectroscopy. Low conductivity polycrystalline films exhibiting cubical structure (bix...

Pulsed laser deposition has been used to grow Pb(Zr0.52Ti0.48)O3 (PZT)/LaNiO3 (LNO) heterostructures with restricted crystallographic orientations on bare Si(001) and SiO2-coated Si(001) substrates, using TiN buffer layers. The effect of background gas pressure on orientation of the thin films was investigated in detail. XRD analyses showed that under optimized conditions, (001)-oriented PZT/LN...
