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 ...
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 ...
Ultracold bosons in random lattice potentials
(Universidade Federal de São Carlos, 2023-04-06)
The Bose-Hubbard model describes short-range interacting spinless bosons on a random lattice. This model is realized in ultracold atomic systems where quantum phase transitions can be observed. When loaded into a deep ...
Electromigration of multiterminal transport bridges
(Universidade Federal de São Carlos, 2023-03-09)
With the continued miniaturization of integrated circuits (ICs), the case of metallic tracks subjected to stress caused by transport currents has become a matter of increasing concern, as it puts at risk the reliability ...
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 ...
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 ...
