Estudo por espectroscopia Raman de efeitos de localização das excitações elementares em superredes e em ligas dopadas.
(Universidade Federal de São Carlos, 2005-03-22)
In the present work, the localization properties of the single-particle and collective excitations subjected to a random potential in the AlGaAsSi alloys and in the intentionally disordered GaAs/AlGaAs:Si superlattices (SL ...
Cálculos de primeiros princípios para BaO.
(Universidade Federal de São Carlos, 2005-02-28)
In this work we present first principles calculations with Density Functional Theory,
DFT, using norm-conserving pseudopotentials. Initially, we perform calculations
of structural properties for metallic barium, Ba, in the ...
Nanoarquitetura em sistemas de alumina anódica porosa e configurações magnéticas de partículas de Co eletrodepositadas.
(Universidade Federal de São Carlos, 2005-10-30)
This thesis presents results on tailoring porous anodic alumina films, the Co-CoO electrodeposition on alumina template and the magnetic behavior of such system. Mono and bi-modal pore distribution at the film surface were ...
