Relaxação de spin em nanoestruturas semicondutoras 0 e 2D
(Universidade Federal de São Carlos, 2023-03-01)
This thesis contains a compilation of the work developed and is divided into
three main parts. The first part describes the homogeneous and inhomogeneous
decoherence mechanisms of excitons in GaAs/AlGaAs quantum wells. ...
Correlation between structure and optical properties of lead metasilicate glass-ceramic under high hydrostatic pressures
(Universidade Federal de São Carlos, 2022-09-21)
Glass structures are determined by not only composition, pressure, and temperature but also by the pressure and thermal histories in which the glass was submitted. In this thesis, a systematic study of these variables was ...
Propriedades óticas e magneto-óticas de monocamadas de MoWSe2
(Universidade Federal de São Carlos, 2023-01-23)
Two-dimensional (2D) semiconductors, such as transition-metal dichalcogenide (TMD) monolayers, have attracted intense interest in the last years because of their direct band gaps, valley properties and excitonic effects. ...
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, ...
