Efeito Aharonov-Bohm em partículas neutras
(Universidade Federal de São Carlos, 2011-03-14)
In classical Physics, the motion of an electrically charged particle is affected only by the presence of a magnetic field if the particle enters a region of space in which the field is present. Meanwhile, in quantum Physics, ...
Propriedades óticas e de transporte em heteroestruturas semicondutoras contendo GaMnAs
(Universidade Federal de São Carlos, 2011-10-14)
In this work, we have investigated Ga1-xMnxAs/GaAs/AlAs quantum wells (QWs) with low Mn concentration (x < 0.1%) grown by Molecular Beam Epitaxy at substrate temperatures of 400 and 450°C. We have investigated the time-resolved ...
