Lattice Expansion of (Ga,Mn)As: The Role of Substitutional Mn and of the Compensating Defects
J. Masek, F. Maca
We apply the density-functional technique to determine the lattice constant of GaAs supercells containing Mn_Ga, Mn_int, and As_Ga impurities, and use a linear interpolation to des…

Disorder-Induced Effects in III-V Semiconductors with Mn
J. Masek, F. Maca
The substitution of Mn in the III-V diluted magnetic semiconductors leads to a strong electron scattering on impurities. Besides the features induced in the valence band by the hyb…

Self-compensating incorporation of Mn in Ga(1-x)Mn(x)As
J. Masek, F. Maca
We consider hypothetical Ga7MnAs8, Ga16MnAs16, and Ga14Mn3As16 crystals with Mn in a substitutional, interstitial, and both positions. Spin-polarized FPLAPW calculations were used…
