Matrizes de reflexão com simetria 𝒰𝑞 [osp(2|2𝑚)(2)]
(Universidade Federal de São Carlos, 2012-03-16)
In this thesis we present solutions of the graded boundary YANG-BAXTER equations for vertex models with 𝒰𝑞 [osp(2|2𝑚)(2)] symmethy.
Nanofios de Ge : síntese e dispositivos
(Universidade Federal de São Carlos, 2012-03-06)
Abstract In this work, germanium nanowires' based devices were studied and developed and the influence of natural disorder on the electronic properties of these structures was also investigated. Parameters related to the ...
Ondas de spin em paredes de domínio unidimensionais em monocamadas magnéticas
(Universidade Federal de São Carlos, 2012-08-16)
Recent investigations on ferromagnetic monolayers predict the existence of spinwave modes without gap in the spectrum, even in the presence of anisotropy. These excitations propagate within the domain walls that exist in ...
Solução numérica das equações de Maxwell para cavidades dielétricas bidimensionais
(Universidade Federal de São Carlos, 2012-08-07)
The objective of this work is to find numerical solutions for Maxwell's equations in two-dimensional dielectric cavities. Such structures can trap light by means of total internal reflections and can be used for constructing ...
Espectroscopia Mössbauer : condições experimentais de aquisição e estocagem multicanal para a análise numérica de dados com adequação de resolução espectral
(Universidade Federal de São Carlos, 2012-02-15)
The objective of this work is to examine the use of Mossbauer spectroscopy in two aspects: the data acquisition, using four different setups and their analysis, comparing three different fittings programs. Concerning to ...
Estados parcialmente emaranhados em comunicação quântica
(Universidade Federal de São Carlos, 2012-03-16)
In this master s thesis we approach the entanglement between quantum states as a resource to be used in the transmission of quantum information, particularly in quantum teleportation. Our focus was directed toward the study ...
Fabricação e caracterização de dispositivos baseados em nanofitas de Óxido de Estanho (SnO2)
(Universidade Federal de São Carlos, 2012-08-06)
The structural and transport features of tin oxide nanobelts synthesized by the vapor-solid method combined with the carbothermal reduction process were investigated in this work. The samples synthesized were characterized ...
Uso de recursos estimuladores da aprendizagem significativa no ensino de física
(Universidade Federal de São Carlos, 2012-07-30)
This research deals with resources which lead to significant learning consistent with the needs of modern society and encourages students to develop knowledge in Physics, in order to enable them to interact with the community ...
Seções de choque da interação de elétrons de energias intermediárias com moléculas poliatômicas e constituintes do DNA
(Universidade Federal de São Carlos, 2012-09-14)
Elastic Differential Cross Sections (EDCS) were measured for the interaction of electrons in the incident energy range of 100-1000 eV, with several polyatomic molecules, namely: ethane (C2H6), propane (C3H8), methanol ...
Propriedades magnéticas de nanofios de cobalto autoformados por deposição à laser pulsado
(Universidade Federal de São Carlos, 2012-02-15)
Le sujet de cette thèse est l étude de nanofils de cobalt dans une matrice d oxyde de cérium (CeO2) épitaxiée sur SrTiO3(001). L auto-assemblage de nanofils a été mis en évidence lors de la croissance de couches minces de ...
