Efeitos de spin em diodos de tunelamento ressonante não-magnéticos tipo-n
(Universidade Federal de São Carlos, 2007-02-27)
In this work, we have investigated spin polarization effects in asymmetric ntype
resonant tunneling diodes (RTDs). When subjected to an external magnetic field parallel
to the tunnel current, the Zeeman effect leads to the ...
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 ...
