Titanium Dioxide (TiO2) thin film has been synthesized using sol-gel method and deposited onto glass substrates using spin coating technique. These thin films are then annealed at various temperatures. The electrical and structural characterizations of the as deposited and annealed films were carried out using IV measurement with 4-point probe equipment and scanning electron microscopy (SEM). From...
In this paper, we report an experimental study on electrochemical anodization using different acidic electrolytes of high purity Ti thin film deposited on silicon substrate by sputtering. The dependence of pore morphology and pore formation rate on process parameters was evaluated. In order to investigate the crystallization, after anodization, samples were annealed in a quartz tube furnace at different...
Successive ionic layer adsorption and reaction technique (SILAR) and solution growth technique have been applied to deposit thin films on amorphous glass substrates. Various parameters, like concentration of complexing agent, pH of the solution, deposition temperature, time, have been optimized to achieve good quality films. Films grown by SILAR method have been found to be non-uniform as confirmed...
This work investigated the electrical and morphological properties of nitrogen doped silicon (NIDOS) thin films. The samples are obtained by LPCVD at low temperature (465degC) by a mixture of disilane (Si2H6) and ammonia (NH3). This stage of deposit is followed by a heat treatment at several temperatures and durations. The resistivity measurements showed an increase in the resistivity values with...
Bulk nanostructured (Bi,Sb)2Te3 compounds and GeTe based amorphous/nanocrystal composites have been successfully fabricated by the combined hydrothermal/hot-pressing and quenching/annealing methods, respectively. The (Bi,Sb)2Te3 nanopowders synthesized by hydrothermal method exhibit a hollow-like structure. After hot-pressing, the nanoscale grains varying from tens to hundreds of nanometers were found...
BiFeO3 -PbTiO3 (BFO-PT) films were synthesized by sol-gel method with the annealing temperatures to be 550degC, 600degC, and 650degC, respectively. The structure and morphology of the films were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The dielectric constant and loss factor are measured. The leakage current density is also performed to check the conductivity...
Iron disilicide based thermoelectric materials with the designed composition Fe1-xMnxAlySi2-y (x = 0.06, 0.08; y = 0, 0.02, 0.04) were prepared by rapid solidification and hot pressing (1193K, 100 MPa, 30 minutes). The effects of Mn+Al double doping were investigated. The influence of pre-annealing on the microstructure and the transport properties were also studied. X-ray diffraction and scanning...
Nanocrystalline thin film tin-oxide microsensors were fabricated on Si3N4 membranes using standard lithography process for the fast detection of reducing gases. The sensing material was spin-coated over platinum electrode contacts with various thicknesses using a sol-gel method. Subsequently, the spin-coated film was gradually heated up to 200 degC in an extended period of 150 mins. After the preannealing...
