Morphology-induced plasmonic resonances in silver-aluminum alloy thin films
We have investigated the optical properties of sputter-deposited silver-aluminum alloy thin films on silicon substrates at room temperature. In addition to the primary feature that corresponds to the bulk plasma resonance, a secondary dip appears in the optical reflectance spectra, which shifts and diminishes with thermal annealing. Careful structural characterization of both the as-deposited a...
متن کاملHigh - temperature emissivities of copper , aluminum , and silver
Using a transient calorimetric technique, the total hemispherical emissivities Eh of very pure copper, aluminum, and silver have been measured at various temperatures in the range 335-1100'K. By carrying out measurements on a sphere, a thin circular disk, and a thin square plate all made of the same copper sample, it is shown that the measured (, is practically independent of the shape of the s...
متن کاملAluminum Oxide-Silver Nanoparticle Interfaces for Memristive Applications
In the present work, a facile approach to construct a nonvolatile resistive random access memory device based on the heterojunction of silver nanoparticles and aluminum oxide is reported. The device structure consisting of Aluminum-Aluminum oxide-Silver Nanoparticles-Aluminum is used to study the charge transport. The current-voltage measurements of this device clearly show the transition from ...
متن کاملON THE REACTIONS IN ILMENITE, ALUMINUM AND GRAPHITE SYSTEM
Al2O3/TiC composites are used as cutting tools for machining gray cast iron and steels. The addition of iron improves the toughness of Al2O3/TiC composites. Ilmenite, aluminum and graphite can be used to produce in-situ Al2O3/TiC–Fe composites. However, the formation mechanism and reaction sequences of this system are not clear enough. Therefore, the present research is designed to determ...
متن کاملDetermination of Silver in Aluminum by Thin Layer Chromatography
Small quantities of silver in technical aluminum can be determined by TLC on the layer of microcrystalline cellulose after separation and concentration by coprecipitation with CdS. The chromatograms were developed by a solvent composed of butanol-methanol-water-nitric acid in the proportion 80 : 5 : 10 : 5 (v/v). Visualisation was made with hydrogen sulfide. After scanning the obtained spots, c...
