Funcionalidades elétricas mediadas por defeitos em óxidos semicondutores do tipo-p
(Universidade Federal de São Carlos, 2023-10-27)
Structural defects, such as point defects, play an important role in the electrical transport in semiconductor oxide films. This work presents a systematic study of photoconductivity at room temperature in thin films of ...
Otimização dos campos de proteção nas técnicas de desacoplamento dinâmico contínuo
(Universidade Federal de São Carlos, 2023-09-15)
In this research project, we investigate the method known as \textit{continuous dynamical decoupling}, which is based on the use of continuously applied external fields to maximize the fidelity of quantum logical operations ...
Influência de Interface sobre as propriedades Ferroicas e Multiferroicas de Nanoestruturas de Pb(Zr0,2Ti0,8)O3/CoFe2O4 Crescidas via RF-Sputtering
(Universidade Federal de São Carlos, 2023-08-11)
This work shows a systematic study of the structural, microstructural, ferroic and multiferroic coupling properties of bilayer thin films of the PZT/CFO system, with the constituent phases varying in thickness from 20 to ...
Desenvolvimento e estudo de memristores baseados em redes de nanofios de SnO2
(Universidade Federal de São Carlos, 2024-01-17)
In this work, memristors were produced based on tin dioxide nanowire networks (𝑆𝑛𝑂2). These nanowires were synthesized by the VLS (Vapor-Liquid-Solid) method. The nanowire structural analysis via X-ray diffraction (XRD) ...
Estudo ab initio de materiais bidimensionais emergentes
(Universidade Federal de São Carlos, 2023-09-28)
Two-dimensional (2D) materials have attracted much attention in the last decade due to their unusual properties such as high degree of anisotropy and chemical flexibility. Since the isolation of a graphene layer, a wide ...
Influência dos defeitos nas funcionalidades elétricas de ZnO, AgO e polianilina
(Universidade Federal de São Carlos, 2023-03-03)
The optical and electrical properties in a semiconductor can be modeled by structural defects. In this thesis, we study the influence of defects on the optical and electronic properties of organic and inorganic semiconductors ...
Magnetic fields as a tool to control superconducting devices
(Universidade Federal de São Carlos, 2023-10-16)
The quantum nature and dissipation-free flow of electric currents in superconducting materials have taken a central role as technological developments push forward the necessity of new methods for processing and dealing ...
Passivação de superfícies de perovskitas via dopagem substitucional
(Universidade Federal de São Carlos, 2023-10-26)
Humanity currently demands new energy sources to replace polluting energy sources and thus restructure the energy matrix in a sustainable manner. In this context, materials science plays a prominent role, as new materials ...
Teoria de controle ótimo aplicada a sistemas quânticos abertos
(Universidade Federal de São Carlos, 2023-11-10)
This thesis, grounded in the field of quantum computing, explores diverse and crucial topics for the advancement of this area. Firstly, we introduce an innovative "double-bang" solution using optimal control theory for ...
