Non-vacuum techniques for the preparation of Cu(In1−xGax)Se2(CIGS) nanoparticle films is reported. CIGS nanoparticles were prepared by mechano-chemical process followed by screen printing and air-brush spray with suitable solvent. Elemental Cu/In/Ga/Se sources were ball milled with different milling times and rates to optimize the conditions to obtain chalcopyrite composition. Under the optimized...
To meet the demands for increased integration and multi functions for multilayer electronic components the related materials and process technique for layer-to-layer interconnection have to be developed together. Using nano-, micro-sized metal powders and epoxy resins conductive via pastes have been formulated. Via conductance was measured before and after solder floating(288 °C) to observe the change...
Porous Silicon (PS) is one of the established materials and can be used in variety of applications in its different forms. Use of monolayer PS film for synthesis of Si QDs is reported here. Nanometer-sized silicon particles are produced by ultrasonic dispersion of thin films in DI water. PS films are characterized using cross sectional scanning electron microscopy and gravimetric analysis while the...
The composite films of amorphous and nanocrystalline Fe73.5Cu1Nb3Si13.5B9 powders/butyl rubber were prepared by pressing in the mold to shape. The piezomagnetic properties of composite films were studied in the temperature range of 20-50 Celsius degree with theshielding properties in the frequency band (30kHz-6000MHz) of electromagnetic wave. The results show that when the microstress below 0.09MPa...
The process of producing finely dispersed Ba1-xSrxTiO3, BaTiO3 and (Bi1-xLax)4Ti3O12 powders with ultra-and nanosized particles by chemical reactions in multi-component salt melts is developed. Also the opportunities of sol-gel method for the film structures formation are used by means of ferroelectric powders inclusion in an oxide silicate matrix. The optimal syntheses condition of film glass-ceramical...
In this paper fabrication of a 0-3 ceramic/ceramic composite lead zirconate titanate, Pb(Zr0.52Ti0.48)O3 thin film has been presented and then a pressure sensor based on multilayer thin-film PZT diaphragm contain of lead zirconate titanate nanocrystalline powders was designed, modeled and optimized. This multilayer diaphragm in general acts as sensor or actuator. ANSYS was used for simulation of diaphragm...
In this work, we report the fabrication process of nanostrutured powder using a Sol-Gel method and HfO2 nanofilms obtained via Pulsed-Laser-Ablation and Electron-Beam Evaporation. The results of the investigation of structural properties and defects of HfO2 nanoparticles and thin films are discussed in terms of the electric quadrupole interactions of the nuclear probe 181Ta within the sample volume...
This paper discussed the surface resistance of carbon nanotube (CNT)/inorganic binder/silver composites film. The used CNT were multiwalled CNT with diameter of 20 nm-40 nm and 5-15 m in length. We used two inorganic binders: sodium metasilicate and tetraethyl orthosilicate (TEOS) and two silvers: nanosilver in powder and solutions. The CNT were separated and dispersed in inorganic binder with different...
Nano-sized powders of transparent conductive aluminum-doped zinc oxide (AZO) have been successfully prepared by electrolysis-modified co-precipitation method. By adding ammonium hydroxide into the precursor solution prepared by electrolytic dissolution of zinc metal in a buffered electrolyte solution of nitric acid and ammonium nitrate with adequate addition of aluminum nitrate, co-precipitate precursors...
