Characterization of metal oxide-based gas nanosensors and microsensors fabricated via local anodic oxidation using atomic force microscopy
(2013) [Artigo de periódico]Thiswork reports on nanoscale and microscalemetal oxide gas sensors, consisting ofmetal-semiconductor-metal barriers designed via scanning probe microscopy. Two distinctmetal oxides, molybdenum and titaniumoxides, were ... -
Cratering and plastic deformation in polystyrene induced by MeV heavy ions : dependence on the molecular weight
(2001) [Artigo de periódico]Cratering and plastic deformation induced by individual MeV ions on the surface of polystyrene thin films of different molecular weights (Mw) (from 3250 to 2 X 10⁷u) are investigated using scanning force microscopy. 20 ... -
Diffusion reaction of oxigen in aluminum oxide films on silicon
(2002) [Artigo de periódico]Aluminum oxide films deposited on silicon by atomic layer chemical vapor deposition were annealed in an ¹⁸O-enriched oxygen atmosphere under various conditions of temperature, time, and pressure. Cavity formation at the ... -
Estudo da influência dos padrões de emissão das espécies do plasma de carbonitretação nas propriedades superficiais de TiCN
(2015) [Artigo de periódico]As intensidades de emissão das espécies N2 +, H, C, NH, N2, Ar e CN do plasma de carbonitretação (usando os gases Ar+N2+CH4) foram medidas por espectroscopia de emissão óptica (OES) em pressão e temperatura constantes ... -
Probing thermomechanical behavior of polymers at the nanometer scale with single-ion bombardment and scanning force microscopy
(2000) [Artigo de periódico]Features produced by swift heavy ions on polymer thin films at different temperatures are used to identify the transition between vitreous and viscoelastic behaviors (the glass transition temperature) and to probe the ... -
Silver nanoparticle thin films deposited on glass surface using an ionic silsesquioxane as stabilizerand as crosslinking agent
(2015) [Artigo de periódico]Thin films containing silver nanoparticles homogeneously dispersed, with narrow size distribution below 10 nm, were synthesized on flat glass surface, by using an ionic silsesquioxane as stabilizer and crosslinking agent. ... -
Strong dependence of the Fe thin-film magnetic anisotropy on the Si(111) substrate preparation
(2003) [Artigo de periódico]We report on the influence of the Si (111) surface preparation on both the structural and the magnetic properties of iron thin films grown onto them. Two different substrate preparation procedures were used, in one of which ...
