Estudo das propriedades estruturais através de espectroscopia Raman de amostras de grafite de poucas camadas (GPC) obtidas por clivagem mecânica
(Universidade Federal de São Carlos, 2011-08-25)
In this work, We report studies on samples of graphite few layers obtained from micromechanical techniques of cleaving Manual of highly oriented pyrolytic graphite (HOPG). In order to checking the number of layers in each ...
Propriedades magneto-óticas e de magneto-transporte de um diodo de tunelamento ressonante contendo Si δ - doping no poço quântico
(Universidade Federal de São Carlos, 2011-03-11)
In this work, we have studied the transport and optical properties of GaAs = AlGaAs resonant tunneling diodes with Si delta-doping at the center of the quantum well. We have studied magneto-transport and polarized resolved ...
Magneto luminescência em diodos de tunelamento ressonante contendo pontos quânticos de InAs
(Universidade Federal de São Carlos, 2011-03-15)
In this work, we have studied the spin polarization of carriers in n-type resonant tunneling diodes (RTDs) of GaAs/AlGaAs which incorporates a single layer of InAs selfassembled quantum dots in the center of the GaAs quantum ...
Síntese e caracterização de compósitos multiferroicos de manganita La: Sr e titanatos de Ba e Sr
(Universidade Federal de São Carlos, 2011-03-18)
In this paper, we seek to prepare composite multiferroics extrinsic whose potential for technological applications, especially in the electronics industry, and the possibility of new phenomena of fundamental scientific ...
A equação de Yang-Baxter para modelos de vértices com três estados
(Universidade Federal de São Carlos, 2011-03-02)
In this work we study the solutions of the Yang-Baxter equation associated to nineteen vertex models invariant by the parity-time symmetry from the perspective of algebraic geometry. We determine the form of the algebraic ...
Efeito de absorção em espalhamento de elétrons por molécula de formaldeido
(Universidade Federal de São Carlos, 2011-10-02)
This master's project's main objective is to study the effects of absorption in the elastic scattering of electrons by molecules of formaldehyde (CH2O). We calculated differential cross sections (SCD), integral cross ...
Ensino significativo de física por projetos: campanha de economia de energia elétrica
(Universidade Federal de São Carlos, 2011-07-29)
This work presents a strategy of meaningful learning based on projects. In the education proposal, steps are suggested to the development of the general design, regardless of the subject to be studied. These steps envolve ...
Estrutura eletrônica de anéis quânticos
(Universidade Federal de São Carlos, 2011-08-09)
The nanoscopic structures with ring topology, or quantum rings, have attracted the interest due to their unique rotational symmetry and the possibility of checking fundamental quantum phenomena. Among them, the study of ...
