Journal ArticleDOI
Molybdenum oxide thin films obtained by the hot-filament metal oxide deposition technique
Mário A. Bica de Moraes,B. Claudio Trasferetti,Francisco Rouxinol,Richard Landers,Steven F. Durrant,Jair Scarminio,Alexandre Urbano +6 more
TL;DR: Molybdenum oxide thin films find diverse applications as catalysts, gas sensors, and electrochromic devices as mentioned in this paper, and are produced mainly by reactive sputtering and thermal evaporation but other...
Journal ArticleDOI
Mechanisms of polymer film deposition from r.f. discharges of acetylene, nitrogen and helium mixtures
Steven F. Durrant,Nei Marçal,Sandra G. Castro,Rita C. G. Vinhas,Mário A. Bica de Moraes,Jorge Humberto Nicola +5 more
TL;DR: In this paper, the authors used optical emission spectroscopy to determine relative concentrations of the key species CH and CN in the plasma as a function of the proportions of monomer gases in the feed, and delineate the behavior of the electron mean energy and number density in the discharge.
Journal ArticleDOI
HMDSO plasma polymerization and thin film optical properties
Rogério Pinto Mota,Douglas S. Galvao,Steven F. Durrant,Mário A. Bica de Moraes,Sócrates O. Dantas,Mauricio Cantão +5 more
TL;DR: In this paper, thin films were deposited from hexamethyldisiloxane (HMDSO) in a glow discharge supplied with radiofrequency (RF) power, and optical properties were determined from transmission ultra violet-visible spectroscopy (UVS) data.
Journal ArticleDOI
Relationships between the plasma environment and the composition and optical-properties of plasma-polymerized thin-films produced in rf discharges of c2h2-sf6 mixtures
TL;DR: In this article, a qualitative explanation of the relationship between the deposition rate and the proportion of SF6 in the feed was given, in good qualitative agreement with the activated growth model, and the refractive index and absorption coefficient of polymers were calculated as a function of the deposition parameters.
Journal ArticleDOI
Properties of titanium oxide films obtained by PECVD
Nilson Cristino da Cruz,Elidiane Cipriano Rangel,Jianjun Wang,B. C. Trasferetti,Celso U. Davanzo,Sandra G. Castro,Mário A. Bica de Moraes +6 more
TL;DR: Amorphous TiO2 films containing carbon and excess oxygen were deposited from glow discharge plasmas of titanium tetraisopropoxide Ti(OC3H7)4, helium, oxygen and argon mixtures as mentioned in this paper.
