Estudo de difusão de impurezas introduzidas por implantação iônica em polímeros
(2003) [Tese]No presente trabalho estudamos de forma sistemática a difusão de impurezas em filmes poliméricos usando as técnicas de implantação iônica e análise por feixe de íons, retroespalhamento Rutherford e de perfil de profundidade ... -
Influence of impurities on the luminescence of Er3+ doped BaTiO3 nanophosphors
(2014) [Artigo de periódico]The influence of the presence of barium carbonate (BaCO3) phase on the luminescence properties of barium titanate nanocrystals (BaTiO3) powders was investigated. Structural and optical characterizations of erbium (Er3+) ... -
Structural and photoluminescence studies of Er implated Be doped and undoped low-temperature grown GaAs
(1999) [Artigo de periódico]Characteristic 1.54 μm Er3+ emission has been observed from Er-implanted and annealed, low-temperature grown GaAs Be doped and undoped samples. Er plateau implantations (480, 155, and 40 keV successive implants) were ... -
Zig-zag networks of self-excited periodic oscillations in a tunnel diode and a fiber-ring laser
(2013) [Artigo de periódico]We report numerical evidence showing that periodic oscillations can produce unexpected andwide-ranging zigzag parameter networks embedded in chaos in the control space of nonlinear systems. Such networks interconnect ...
