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 ...
Manipulação de spin em diodos de tunelamento ressonante não-magnéticos tipo-n
(Universidade Federal de São Carlos, 2010-04-01)
The aim of this work was to study the spin effects in non-magnetic asymmetric n-type resonant tunneling diodes (RTD). For this purpose, we have used transport and polarization resolved magneto-photoluminescence measurement ...
Efeitos de spin em diodos de tunelamento ressonante tipo-p
(Universidade Federal de São Carlos, 2012-03-27)
In this work, we have investigated the spin effects in p-i-p GaAs/AlAs resonant tunneling diodes under magnetic field parallel to the tunnel current. The spin-dependent tunneling of carriers was studied by analyzing the ...
