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 ...
Fabricação e caracterização elétrica de dispositivos orgânicos emissores de luz derivados de poli-p(fenilene vinilene) (PPV)
(Universidade Federal de São Carlos, 2010-03-16)
Molecularly doped polymers have been widely studied in recent years due to their electronic and optical properties, and application in the manufacture of opto-electronic devices, light emitting diodes (LED) and others. ...
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 localização de portadores em poços quânticos de GaBiAs/GaAs
(Universidade Federal de São Carlos, 2015-08-04)
In order to investigate optical and spin properties of GaBiAs / GaAs quantum
wells, we performed both photoluminescence and magneto-photoluminescence
spectroscopy measurements in three samples: 10 nm quantum wells with ...
Effective-action approach to dirty bosons in optical lattices
(Universidade Federal de São Carlos, 2019-02-21)
A system of cold bosonic atoms loaded in an optical lattice potential can undergo a macroscopic phase transition due to quantum fluctuations. As the depth of the lattice potential is increased, the ground state of the ...
Armadilha Óptica de Dipolo para 88Sr
(Universidade Federal de São Carlos, 2019-02-28)
In this work, we present the study of light and matter interaction through the building and operation of a cold atoms experiment. The motivation is to study light scattering in the dense regime, where this phenomenon becomes ...
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 ...
