Caracterização ótica de poços quânticos de GaMnAs
(Universidade Federal de São Carlos, 2007-09-12)
In this work, we have studied GaAs/AlAs/Ga1-xMnxAs quantum wells (QWs) with low Mn concentration ( 0 < x < 0,2%). The samples were grown by Molecular Beam Epitaxy (MBE) in high temperature (450 C). The growth conditions ...
Efeitos de localização de portadores em poços quânticos de GaBiAs/GaAs
(Universidade Federal de São Carlos, 2015-08-04)
In order to investigate optical and spin properties of GaBiAs / GaAs quantum
wells, we performed both photoluminescence and magneto-photoluminescence
spectroscopy measurements in three samples: 10 nm quantum wells with ...
Caracterização das propriedades ópticas e de spin de poços quânticos de InGaAsN/GaAs
(Universidade Federal de São Carlos, 2015-03-30)
In this work, it was investigated the optical and magneto-optical properties of In- GaAsN/GaAs and InGaAs/GaAs double quantum wells. It was performed a systematic experimental study of photoluminescence (PL) as a function ...
