Low-temperature deposition of silicon oxide and silicon nitride by reactive magnetron sputtering
(ELSEVIER SCI LTD, 2009)
In this study, oxide and nitride films were deposited at room temperature through the reaction of silicon Sputtered by argon and oxygen ions or argon and nitrogen ions at 250 and 350 W with 0.67 Pa pressure. It was observed ...
Characterization of Silicon Rich Oxides with Tunable Optical Band Gap on Sapphire Substrates by Photoluminescence, UV/Vis and Raman Spectroscopy
(Soc Quimica MexicoMexico D FMéxico, 2008)
Study of oxide bands in p-type porous silicon layers
The interest in developing fast and reliable chemical and biochemical sensors in an inexpensive way is something that has attracted a lot of efforts in the last decades. One of the potential material candidates is ...
Photoluminescence in silicon/silicon oxide films produced by the Pulsed Electron Beam Ablation technique
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
In this work we report studies of the photoluminescence emission in samples based on Si/SiOx films deposited by the Pulsed Electron Beam Ablation (PEBA) technique. The samples were prepared at room temperature using targets ...
Infrared study of the oxidation of porous silicon: evidence of surface modes
(Wiley VCH Verlag, 2009-02)
Porous silicon is characterized by a large specific area and a large chemical reactivity. These characteristics, although attractive for sensing applications, led to an unstable behaviour. Different oxidation methods have ...
Oxidized Silicon Nanoparticles and Iron Oxide Nanoparticles for Radiation Therapy
Our research objective is to develop superparamagnetic iron oxide nanoparticles and silicon nanoparticles as radiosensitizers for cancer therapy. After internalization by breast tumor cells and irradiation with X-rays, the ...
Structural properties of porous silicon/SnO2:F heterostructures
(Elsevier Science Sa, 2012-04)
In this work we present structural studies made on SnO2 deposited on macroporous silicon structures. The porous silicon substrates were prepared by anodization of p-type silicon wafers. The SnO2 doped layers were synthesized ...
