Controle da emissão visível de nanopartículas baseadas em óxido de zinco
(Universidade Federal de São Carlos, 2021-02-25)
We present a study of the synthesis processes and of the structural, vibrational and optical properties of Zn1-xCdxO nanostructured system. The Zn1-xCdxO samples were synthesized using mechanosynthesis method, in the ...
Deposição e caracterização de filmes finos do sistema Zn(1-x)CoxO obtidos por spray pirólise para aplicação em sensor de ozônio
(Universidade Federal de São Carlos, 2021-04-19)
The current concern about reducing the harmful effects of air pollution on environment and human health requires adequate gas sensors that allow an efficient control and monitoring on a wide range of pollutants. This ...
Propriedades ópticas e magneto-ópticas de monocamadas de dicalcogenetos de metais de transição
(Universidade Federal de São Carlos, 2022-06-07)
Bidimensional (2D) materials are systems of great interest both from the fundamental physical point of view and for possible applications in electronics, optoelectronics and spintronics. In this thesis, the optical properties ...
Correlation between structure and optical properties of lead metasilicate glass-ceramic under high hydrostatic pressures
(Universidade Federal de São Carlos, 2022-09-21)
Glass structures are determined by not only composition, pressure, and temperature but also by the pressure and thermal histories in which the glass was submitted. In this thesis, a systematic study of these variables was ...
Relaxação de spin em nanoestruturas semicondutoras 0 e 2D
(Universidade Federal de São Carlos, 2023-03-01)
This thesis contains a compilation of the work developed and is divided into
three main parts. The first part describes the homogeneous and inhomogeneous
decoherence mechanisms of excitons in GaAs/AlGaAs quantum wells. ...
