Dye-sensitized solar cells (DSSCs) are fabricated using a novel 3C-SiC/TiO(2) nanocomposite as a photoelectrode to enhance the power conversion efficiency. Compared with a pristine nanocrystalline TiO(2) cell, a DSSC based on a 3C-SiC (0.04 wt%)/TiO(2) nanocomposite photoelectrode shows ~115% increase in power conversion efficiency.

Flexible capacitive pressure sensors fabricated with nanocomposites were experimentally characterized and results compared with simulations from analytical modeling. Unlike traditional diaphragm silicon pressure sensors, the flexible nanocomposite sensors present a linear response over a large pressure range due to the changes in the volume of the dielectric that cause the pressure inside the d...

A Polyaniline/Manganese dioxide (PANI/MnO2) nanocomposite contains five weight percentages of MnO2. It has been successfully prepared by in situ polymerization. The structural, optical, and conductivity of nanocomposites remain relative to changes with respect to the weight percentage of MnO2. The structural, morphological, optical, and electrical conductivity i...

improving barrier properties through the use of nanocomposites is an important area of research, especially for the food packaging industry. in this work, titanium dioxide (tio2 )/low density poly ethylene (ldpe) nanocomposites were synthesized as the oxygen barrier layers through the co-extrusion process. the oxygen permeability of the nanocomposite with 4% of tio2 decreased for about 16% comp...

Ellipsometric determination of optical constants for silicon and thermally grown silicon dioxide via a multi-sample, multi-wavelength, multi-angle investigation" (1998). Optical constant spectra for silicon and thermally grown silicon dioxide have been simultaneously determined using variable angle of incidence spectroscopic ellipsometry from 0.75 to 6.5 eV. Spectroscopic ellipsometric data set...

We have found that the deposition of critical optical thin film stacks with silicon dioxide from an electron beam gun is severely limited by the stabilty of the evaporation pattern of the material. We had not obtained satisfactory results in some of the more demanding applications with either solid or granular starting material. The amount of material deposited on a central monitor chip or cont...

Paper presents a numerical analysis of quantum states and probability ψψ* function of a Si/SiO2 nanostructure in varying electrostatic field. The position of probability function peak xp is traced and the bias, under which it abandons the structure (emission or discharging bias), is determined. Variations of the ground state energy with the bias is also examined. The Poisson Schrödinger model o...

Carbon nanotube adhesion force measurements were performed on single-walled nanotubes grown over lithographically defined trenches. An applied vertical force from an atomic force microscope (AFM), in force distance mode, caused the tubes to slip across the 250-nm-wide silicon dioxide trench tops at an axial tension of 8 nN. The nanotubes slipped at an axial tension of 10 nN after being selectiv...

The narrowest feature of an integrated circuit is the silicon dioxide gate dielectric (3±5 nm). The viability of future CMOS technology is contingent upon thinning the oxide further to improve drive performance, while maintaining reliability. Practical limitations due to direct tunneling through the gate oxide may preclude the use of silicon dioxide as the gate dielectric for thicknesses less t...

Metallic-dielectric nanocomposites, including Ag-SiO2, Co-SiO2 and WC-SiC, were synthesised on silicon substrates using ion implantation. The electron field emission (FE) properties of these nanocomposites were studied and correlated to their microstructure determined from the measurements of atomic force microscopy, Rutherford backscattering spectroscopy, x-ray photoelectron spectroscopy and t...
