Obtenção, caracterização e avaliação da performance fotocatalítica de nanoestruturas de TiO2 contendo metais de transição (Nb e W)
(Universidade Federal de São Carlos, 2022-04-18)
Heterogeneous photocatalysis has been considered a promising alternative for the removal of several organic pollutants linked to environmental pollution. Among a range of materials currently used, titanium dioxide (TiO2), ...
Propriedades óticas e elétricas de dicalcogenetos de metais de transição sobre talco
(Universidade Federal de São Carlos, 2022-02-24)
Two-dimensional (2D) systems have attracted great attention in the last years, for
fundamental physics and in potential applications as optoelectronic devices. There is a great interest in transition metal dichalcogenides ...
Sensores baseados em nanofios semicondutores de SnO2: fotodetector de luz UV e sensor de gás
(Universidade Federal de São Carlos, 2022-04-11)
In this work, sensors employing SnO2 semiconductor nanowires as active layer for gas
and light detection were built. SnO2 nanowire samples were grown by VLS (VapourLiquid-Solid) method and morphological and structural ...
Dos conceitos fundamentais da termodinâmica ao resetting de computadores quânticos
(Universidade Federal de São Carlos, 2022-04-18)
Thermodynamic has been known and studied for centuries, whereas the field of computing, more specifically quantum computing, is new and currently a lot of research has being done to understand and develop this field of ...
Desenvolvimento de nanoestruturas de TiO2 com superfície modificada pela presença de espécies de Fe e a avaliação da sua performance fotocatalítica
(Universidade Federal de São Carlos, 2022-07-29)
The development of society has increasingly demanded technological evolution in order to supply its needs, resulting in environmental costs that can lead to severe damage. Among these impacts, the pollution of springs and ...
O efeito Zeno no controle da evolução adiabática de um sistema quântico a partir de medidas não-seletivas
(Universidade Federal de São Carlos, 2022-07-26)
The objective of the present work is to improve the performance of a Stimulated Raman Adiabatic Passage (STIRAP) in a 3-level system by applying successive non-selective measurements throughout the evolution (exploiting ...
Incompressible energy spectrum in atomic Bose-Einstein condensates: a weak wave turbulence theory approach
(Universidade Federal de São Carlos, 2022-08-25)
Bose-Einstein condensates with their superfluidity property provide an interesting parallel to classical fluids. Due to the Kolmogorov spectrum of homogeneous turbulence the statistics of the incompressible velocity field ...

This work consists in a complexity analysis of an algorithm for solving differential equations,
which shares common characteristics with other algorithms designed for the same task.
Operations such as state preparation, ...
Propriedades ópticas de filmes semicondutores GaAsBi e GaSbBi
(Universidade Federal de São Carlos, 2022-05-02)
Bismuth-diluted III-V are interesting materials for possible applications in optoeletronic and spintronic devices. If we add a small amount of Bi in III-V materials, we observe a strong reduction in the band gap energy. ...
Electromagnetically induced transparency under effects of light-mediated interactions, entanglement generation, and Fock states detection
(Universidade Federal de São Carlos, 2022-10-25)
This thesis presents a brief compilation of the works developed during my doctorate, and can be divided basically into three main parts. In the first one, we show the changes caused by considering long-range interactions ...
