Estado polarônico de elétrons em canais quase unidimensionais na superfície de hélio líquido
(Universidade Federal de São Carlos, 1998-08-18)
In this work, we have investigated the polaronic state formed in the system of surface electrons
confined in a quasi-one-dimensional channel over liquid helium. The electrons bound to the surface
by a holding electric ...
Relações estrutura: propriedades como subsídio à elucidação do diagrama de fases do sistema ferroelétrico (Pb,Ca)TiO3
(Universidade Federal de São Carlos, 2013-02-28)
Solid solutions with perovskite structure, especially lead-based oxides, have been developed and investigated as single crystal and/or polycrystal ceramics since the midtwentieth century, but aspects of phase diagram of ...
"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. ...
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 ...
Efeitos de parâmetros de crescimento nas propriedades ópticas de filmes finos de ZnO:Er
(Universidade Federal de São Carlos, 2019-12-19)
We report a systematic study on the structural, morphological and optical properties of Er-doped ZnO thin films grown by Spray Pyrolysis. The films were deposited on glass substrates between 230ºC - 300ºC, using as precursors ...
Dos conceitos fundamentais da termodinâmica ao resetting de computadores quânticos
(Universidade Federal de São Carlos, 2022-04-18)
Thermodynamic has been known and studied for centuries, whereas the field of computing, more specifically quantum computing, is new and currently a lot of research has being done to understand and develop this field of ...
Estudo de algoritmos quânticos para resolução de equações diferenciais parciais
(Universidade Federal de São Carlos, 2022-05-02)
With great impact in various areas of engineering and mathematics, quantum computing is an emerging technology with one of its applications in resolving large-scale mathematical problems, such as optimization and simulation. ...
