A semiquantitative approach to the impurity-band-related transport properties of GaMnAs nanolayers
E. J. R. de Oliveira, E. Dias Cabral, M. A. Boselli +1
We investigate the spin-polarized transport of GaMnAs nanolayers in which a ferromagnetic order exists below a certain transition temperature. Our calculation for the self-averaged…
Impurity bands and the character of the electronic states in ferromagnetic GaMnAs layers
E. Dias Cabral, M. A. Bosellli, A. T. da Cunha Lima +1
The interplay between disorder and spin polarization in a GaMnAs thin layer results into spin-polarized impurity hole bands. A figure of merit is defined to label the hole state as…
Spin-polarized transport in ferromagnetic multilayered semiconductor nanostructures
E. J. R. Oliveira, A. T. da Cunha Lima, M. A. Boselli +3
The occurrence of inhomogeneous spin-density distribution in multilayered ferromagnetic diluted magnetic semiconductor nanostructures leads to strong dependence of the spin-polariz…
Spin-polarized transport in GaMnAs multilayers
L. Loureiro da Silva, M. A. Boselli, X. F. Wang +2
The spin-dependent mobility for the lateral transport of the hole gas in a GaMnAs/GaAs heterostructure containing several metallic-like ferromagnetic layers is calculated. The elec…
Frictional drag between non-equilibrium charged gases
X. F. Wang, I. C. da Cunha Lima
The frictional drag force between separated but coupled two-dimensional electron gases of different temperatures is studied using the non-equilibrium Green function method based on…
Hole spin polarization in GaAlAs:Mn structures
A. Ghazali, I. C. da Cunha Lima, M. A. Boselli
A self-consistent calculation of the electronic properties of GaAlAs:Mn magnetic semiconductor quantum well structures is performed including the Hartree term and the sp-d exchange…
