Equação mestra microscópica para o modelo de Rabi
(Universidade Federal de São Carlos, 2013-02-27)
The Rabi model is the most complete one has to describe the interaction between radiation and matter. However, as it is difficult to obtain the exact solution to this model, many of recent atom-field studies have used the ...
Movimento de paredes de domínio ferroelétricas com luz: descrição teórica e investigação do fenômeno em materiais policristalinos
(Universidade Federal de São Carlos, 2019-04-05)
Ferroelectrics are material exhibiting a spontaneous polarization that may be switched by
an electric external field. This behavior is provided to well-known ferroelectric domain
walls motion. Recent research has proved ...
Inibição enzimática analisada com uma abordagem da mecânica estatística
(Universidade Federal de São Carlos, 2019-02-21)
In the conventional approach of Biochemistry, a parameter for the description of the functioning of an enzyme is the rate of conversion of substrate into product in the presence or absence of an inhibitor. Given this ...
Estudo de propriedades estruturais, vibracionais, ópticas e magnéticas em amostras de Pb1-xCoxTiO3: transição de fase induzida por composição, temperatura e pressão
(Universidade Federal de São Carlos, 2019-03-29)
This work presents a study of the synthesis and characterization of structural, vibrational, optical and magnetic properties of the compound Pb1-xCoxTiO3 (PCoT). The PCoT samples were synthesized using the Solid State ...

Spray pirólise de filmes de óxido de zinco dopado com alumínio e estanho
(Universidade Federal de São Carlos, 2019-07-02)
We present a study on the structural, optical and electrical properties of ZnO doped with Al (ZnO: Al) and with Sn (ZnO: Sn) grown on glass substrates using the Spray Pyrolysis technique. The sample were grown in the ...
Do geocentrismo à gravitação universal: proposta e implementação de uma sequência didática para o ensino médio
(Universidade Federal de São Carlos, 2016-08-18)
This work is formed by the development and implementation of an Educational Product, which by means of a didactic sequence (DS), aimed to address geocentrism, heliocentrism and universal gravitation topics in a less classical ...
Development of seminconductor nanowire materials for electronic and photonics applications
(Universidade Federal de São Carlos, 2019-12-05)
The thesis is concerned with study of GaAs nanowires fabricated on Si substrate.
The possibility of growing III-V semiconductor materials directly on silicon in the
form of nanowires is an attractive route to the integration ...
