Filmes de diamante não-dopados e dopados: um estudo sistemático usando espectroscopia Raman
(Universidade Federal de São Carlos, 2004-11-17)
Diamond films grown by both hot filament (HFCVD) and microwave-plasma (MW-CVD) assisted chemical vapor deposition were investigated. Raman spectroscopy, scan-
ning electron microscopy and X-ray di¤raction were employed ...
Correlações intrínsecas em sistemas tipo-Dirac confinados por um campo magnético constante
(Universidade Federal de São Carlos, 2024-07-04)
The Weyl-Wigner formalism in phase space is investigated in the context of Dirac spinors as qubits correlated by continuous degrees of freedom. The extension to relativistic equations connects quantum mechanical phenomena ...
Critical phenomena in rock-paper-scissors model
(Universidade Federal de São Carlos, 2024-05-07)
This work presents a study on the dynamics of the Rock-Paper-Scissors (RPS) model, with particular emphasis on the influence of variations of the control parameters on the emergence and dissipation of spatial patterns as ...
Break of reciprocity on the light scattered by a disordered atomic cloud
(Universidade Federal de São Carlos, 2024-03-07)
This study delves into interference phenomena, specifically exploring interference patterns arising from light scattered by a disordered assembly of cold atoms. The investigation focuses on disrupting optical path reciprocity ...
Propriedades ópticas e magneto-ópticas de heteroestruturas WSe2/ β-Ga2O3
(Universidade Federal de São Carlos, 2024-03-22)
Transition metal dichalcogenides (TMDs) have been the subject of intense study in recent years due to their unique properties. In their three-dimensional configuration (3D), they are known as indirect bandgap semiconductors, ...
Algoritmo quântico para o problema de gerenciamento de estoque
(Universidade Federal de São Carlos, 2023-11-24)
In this work, we developed a quantum algorithm in Adiabatic Quantum Computing for the Inventory Management Problem, adapted for factories that use gravitational shelves as the standard storage system. The main goal of the ...
Platforms for quantum information and technology
(Universidade Federal de São Carlos, 2024-02-29)
This work presents a collection of scientific research results in the field of quantum information. The first paper describes the mathematical properties of a particular type of state of light, called the two-mode squeezed ...
Propriedades microestruturais e elétricas de nanoestruturas de WO3 puras e dopadas com Mn
(Universidade Federal de São Carlos, 2024-05-21)
Tungsten trioxide (WO3) is an n-type wide bandgap semiconductor that has been widely studied due to its properties, being used in the generation of electricity “water splitting”, catalysis, gas sensors, among others. ...
Dicalcogenetos de metais de transição em poucas camadas: o papel das espécies de calcogênio e suas propriedades não convencionais
(Universidade Federal de São Carlos, 2024-06-10)
Two-dimensional (2D) Transition Metal Dichalcogenides (TMDs) constitute the most
studied class of 2D materials after graphene, as they have a variety of applications already
demonstrated in the laboratory, including ...
