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 ...
Engenharia de defeitos em semicondutores de gap largo
(Universidade Federal de São Carlos, 2015-12-14)
Defects play a fundamental issue on physical properties of wide bandgap semiconductors
(WBS) due to the possibility of application in high temperature. This work shows the features of the defects in di erent kind of WBS ...
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 ...
