The unit cell has 64 atoms, so that one manganese (Mn) atom is placed in the position of gallium site, which corresponds to 3.125 % doping concentration with x = 12.5 %. Our calculations, using local density approximation + U (Hubbard parameter) scheme, predict that the ferromagnetic state for AlGaMnAs, with a magnetic moment of about 4.014 μB per Mn dopant is more favorable. Despite its electronic properties being strongly affected by inducing small amounts of Mn substitutional atoms in the cationic sublattice of AlGaAs, (Al x Ga1-x )1-y Mn y As possesses optical properties strictly less than those of Al x Ga1-x As, especially its optical conductivity at the peak 1.256 eV. The results indicate that AlGaMnAs may be a good candidate for optoelectronics when exploited in optical fiber networks, and it can still be of great interest because of its promising potential when used for spintronics. 2013-08-02T02:20:42Z 2013-08-02T02:20:42Z 2013-01 Article Journal of Materials Science, vol. 48(2), 2013, pages 758-764 0022-2461 http://link.springer.com/article/10.1007%2Fs10853-012-6792-5 http://hdl.handle.net/123456789/27295 en Springer Science+Business Media, LLC |
