In recent years, the demand for thin film coatings on large area substrates has been rapidly increasing. Coating is some times required to make an object harder, or to provide the surface with particular electrical and optical properties. Hence, research on thin film science has received much attention due to its tremendous applications in modern technology. The importance of coatings and the s...

Charge trapping/detrapping within thin solid films of the organic photoconductive materials Sudan I and Disperse Red I was investigated. Charge trapping took place under an external bias upon irradiation. Trapped charges could be stored for long times in the dark under open-circuit or short-circuit conditions and could be removed (detrapped) with irradiation at short-circuit. These substances s...

Active matrix liquid crystal display (AMLCD) is the most widely used display technology nowadays. Transparent display is one of the emerging technologies to provide people with more features such as displaying images on transparent substrates and simultaneously enabling people to see the scenery behind the panel. Polymer-dispersed liquid crystal (PDLC) is a possible active matrix transparent di...

With attention to the thin film structure of colloidal quantum dot solar cells, in this paper in order to improvement of active layer absorption of them, we have proposed the use of nanostructure pattern for enhancement of their performance. For this purpose we have presented suitable nano hemisphare patterns in colloidal quantum dot solar cells for light trapping in absorption layer. Then with...

Radial n-i-p structure silicon nanowire (SiNW)-based microcrystalline silicon thin-film solar cells on stainless steel foil was fabricated by plasma-enhanced chemical vapor deposition. The SiNW solar cell displays very low optical reflectance (approximately 15% on average) over a broad range of wavelengths (400 to 1,100 nm). The initial SiNW-based microcrystalline (μc-Si:H) thin-film solar cell...

In this work, nanostructured TiO2 and Cr-doped TiO2 thin films were deposited on glass substrate through sonochemical-chemical vapor deposition (CVD) method. The resulting thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible absorption spectroscopy, and photoluminescence spectroscopy techniques. The TiO2 thin film has nanocubic morphology and ...

A power management controller circuit with a switched-capacitor mode down-regulator and a battery charger block for semi-active radio-frequency identification (RFID) tags was proposed and fabricated. The major achievement of the proposed switched-capacitor mode downregulator and battery charger block is providing a low standby current internal voltage supply circuit and self-controlled thin fil...

©ALLVIA, Inc. 2011 Sunnyvale, CA www.allvia.com Page 1 Interposers between ICs and package substrates that contain thin film capacitors have been used previously in order to improve circuit performance. However, with the interconnect inductance due to wire bonds being high, the benefits of thin film capacitors have not been fully realized. Replacing the wire bonds with Through Silicon Vias (TSV...

thin film phthalocyanines(pc), incloding zinc, iron, and magnesium phthalocyani-nes, were prepared by vacuum deposition method. chronocoulometry was used to study the charge transfer reaction mechanism of ionic species through the thin films. the results obtained in chronocoulometric studies shows that the thin film phthalocyanines could operate via two mechanisms.the first mechanism metal pc t...
