Theoretical and experimental investigation on the visible-light controlled functional properties in charged domain wall ferroelectrics
(Universidade Federal de São Carlos, 2023-04-13)
Optical control of ferroelectric properties have been attracted a growing interest as an
alternative to the conventional control by applied electric fields. However, the major
drawback for achieving an effective reversible ...
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 ...
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 ...
Propriedades magnéticas e magnetoelétricas de compósitos multiferroicos de Pb[Zr0,53Ti0,47]O3/NixCo1-xFe2O4
(Universidade Federal de São Carlos, 2023-10-27)
New technologies are arising from the research and development of magnetism, especially those related to processing, information storage and sensors, are becoming increasingly important. in this regard, magnetoelectric ...
The memristive response in solids
(Universidade Federal de São Carlos, 2023-08-07)
In this Master Thesis, we have investigated basic ingredients of the theory of solid state
transport, namely the Drude like conductivity and the activation of nonequilibrium charge
carriers subjected to a relaxation time, ...
