Estudo experimental de efeitos de spin em heteroestruturas semicondutoras
(Universidade Federal de São Carlos, 2015-04-28)
In this thesis, we have investigated optical and spin properties of semiconductor
nanostructures. Photoluminescence and magneto-photoluminescence measurements
were performed in high magnetic field (B ≤ 15T), in GaBiAs ...
Processamento e propriedades do sistema ferroelétrico (Li,K,Na)(Nb,Ta)O3 dopado com CuO
(Universidade Federal de São Carlos, 2015-03-09)
The search for new lead-free piezoelectric materials has been a major goal of many scientists in recent years. The main cause is the replacement of widely used lead zirconate titanate (PZT) based ceramics due to the highly ...
Efeito da modulação da topologia do confinamento em sistemas quase zero-dimensionais induzida por campo elétrico
(Universidade Federal de São Carlos, 2015-04-01)
Quantum dots grown by epitaxial techniques for optical and transport studies are usually capped by a layer of the same material on which the QDs were grown. Recently, several studies have shown how the growth parameters ...
