Suppression of the green emission, texturing, solute-atom diffusion and increased electron-phonon coupling induced by Ni in sol-gel ZnNiO thin films
(Elsevier Science, 2018-10)
Zn1−xNixO thin films (nominal x = 0, 0.01, 0.02, 0.04, 0.1 and 0.2) were synthesized on silicon substrates through a sol-gel/dip-coating technique. Samples were studied by X-ray diffraction, scanning electron microscopy, ...
Decay of photo-induced conductivity in Sb-doped SnO2 thin films, using monochromatic light of about bandgap energy
(2013-02-15)
Doping tin dioxide (SnO2) with pentavalent Sb5+ ions leads to an enhancement in the electrical conductivity of this material, because Sb5+ substitutes Sn4+ in the matrix, promoting an electronic density increase in the ...
Nanotubos de carbono funcionalizados e imobilizados em fibras de soja: avaliação da citotoxicidade, adesão celular e potencial aplicação biomédica
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA MECÂNICA, 2017-08-14)
The multiwalled carbon nanotubes (MWCNT) incorporated into the materials of protein origin can contribute to the emergence of interesting composite biomaterials with great potential of biological applications. MWCNT are ...
Fotoluminescência e transporte elétrico em 'SNO IND. 2' dopado com os íons terras-raras 'ER POT. 3'/' e 'EU POT. 3'/'
(Universidade Estadual Paulista (Unesp), 2008-02-28)
Através do processo sol-gel, foi sintetizado o material semicondutor dióxido de estanho ('SNO IND. 2') dopado com as terras-raras 'ER' e 'EU', sendo obtidas amostras na forma de xerogéis (pós) e filmes finos, neste último ...
Desenvolvimento e caracterização de dispositivos para reposição de filmes finos por descarga em cátodo oco
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2006-12-15)
In the present work we use a plasma jet system with a hollow cathode to deposit thin TiO2 films on silicon substrates as alternative at sol-gel, PECVD, dip-coating e magnetron sputtering techniques. The cylindrical cathode, ...
