Quantum theory of the effect of grain boundaries on the electrical conductivity of thin films and wires
(Elsevier, 2015)
We calculate the electrical conductivity of a metallic sample under the effects of distributed impurities
and a random distribution of grain boundaries by means of a quantum mechanical procedure based on
Kubo formula. ...
Photochemical deposition, characterization and optical properties of thin films of ThO2
(Elsevier Ltd, 2019)
Thorium oxide thin films were successfully prepared by direct UV irradiation of amorphous films composed of thorium(IV) β-diketonate precursor complexes on Si(100) and quartz substrates. The ThO2 films were characterized ...
Alkanethiol self-assembled monolayer on copper polycrystalline thin films: influence on resistivity
(Elsevier, 2018)
Thin polycrystalline copper films of low surface roughness and low electrical resistivity were deposited by physical vapor deposition onto mica at room temperature and in thicknesses ranging from 10 to 80 nm. The crystalline ...
Polymer-based nanocomposites: In situ generation and immobilization of gold nanoparticles on poly(n-vinyl-2-pyrrolidone) and poly(ϵ-caprolactone) thin films
(American Scientific Publishers, 2017)
Copyright © 2017 American Scientific Publishers All rights reserved. In this work, we report an interesting method for simultaneous obtaining and immobilization of gold nanoparticles onto polymer thin films. Polymer-based ...
Resistivity induced by a rough surface of thin gold films deposited on mica
(ELSEVIER, 2005-03-16)
A central question regarding thin metallic films is how does the roughness of the film affect its electrical transport properties, when its thickness is comparable to or smaller than the electron mean free path. The drive ...
Ibuprofen, Carbamazepine and β-Estradiol Determination Using Thin-Film Microextraction and Gas Chromatography-Mass Spectrometry
(Sociedad Brasileira de Quimica, 2016)
The use of thin-film microextraction for the extraction of selected pharmaceutical compounds followed by gas chromatography-mass spectrometry detection was evaluated. A segment of polysiloxanes polymer sheet was used as ...
Study of the influence of Er/Ln co-doping in La2O3 thin films on their up-conversion properties (where Ln ¼ Ho or Nd)
(Elsevier, 2020)
In this study we report significant enhancement of up-conversion emissions of La2O3:Er thin films when they are co-doped with Er/Ln (where Ln = Nd or Ho). The proposed mechanisms by which the Ln ions contribute to these ...
A photochemical proposal for the preparation of ZnAl2O4 and MgAl2O4 thin films from beta-diketonate complex precursors
(Elsevier, 2016)
ZnAl2O4 and MgAl2O4 thin films were grown on Si(100) and quartz plate substrates using a photochemical method in the solid phase with thin films of beta-diketonate complexes as the precursors. The films were deposited by ...
Titanium monoxide ultra-thin coatings evaporated onto polycrystalline copper films
(Elsevier, 2004)
We evaporated polycrystalline copper thin films of thickness between 10 and 100nm on silicon substrates with their
native oxide under ultra-high-vacuum conditions. Some of them were exposed to air for a period ranging ...
Resistivity and Hall voltage in gold thin films deposited on mica atroom temperature
(Elsevier, 2015)
We report the thickness dependence of the resistivity measured at 4 K of gold films grown onto mica atroom temperature (RT), for thickness ranging from 8 to 100 nm. This dependence was compared to theone obtained for a ...
