Caracterização ótica de poços quânticos de GaMnAs
(Universidade Federal de São Carlos, 2007-09-12)
In this work, we have studied GaAs/AlAs/Ga1-xMnxAs quantum wells (QWs) with low Mn concentration ( 0 < x < 0,2%). The samples were grown by Molecular Beam Epitaxy (MBE) in high temperature (450 C). The growth conditions ...
"Probabilidades negativas" e tomografia de Qubits
(Universidade Federal de São Carlos, 2007-03-28)
In this dissertation we approached the tomography of discrete systems, understood as the representation
and the reconstruction of states. For the tomography we used distribution functions
of symmetrical pseudo-probabilities. ...
Caracterização do módulo elástico por espectroscopia mecânica da liga Ti-13Nb-13Zr
(Universidade Federal de São Carlos, 2009-09-11)
In the present time the titanium and their alloys are begin widely studied in the field of
biomaterials because of its suitable mechanical properties such as low elastic
modulus, excellent corrosion resistance and high ...
Propriedades de transporte eletrônico em filmes de diamante crescidos por deposição de vapores químicos
(Universidade Federal de São Carlos, 2007-02-27)
In this work it was investigated some fundamental properties of undoped and Borondoped
(p-type) synthetic diamond films. It was investigated the influence of the cleaning
process on the surface s quality in order to ...
Processamento e caracterização de cerâmicas eletro-ópticas do sistema ferroelétrico (Pb1-xLax)TiO3
(Universidade Federal de São Carlos, 2006-08-04)
The ferroelectric titanate of lead modified with Lanthanum metal system (or PLT) is the most studied of the perovskite structure. It is known that ceramic bodies with specify compositions and adequately chemical preparations ...
