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…
Compositional Dependence of Formation Energies of Substitutional and Interstitial Mn in Partially Compensated (Ga,Mn)As
J. Masek, I. Turek, J. Kudrnovsky +2
We use the density-functional theory to calculate the total energy of mixed crystals (Ga,Mn)As with a small concentration of various donors. We find that the formation energy of Mn…
Ferromagnetic transition temperature enhancement in (Ga,Mn)As semiconductor by carbon co-doping
T. Jungwirth, J. Masek, Jairo Sinova +1
We present a theoretical study of (Ga,Mn)(As,C) diluted magnetic semiconductors with high C acceptor density that combines insights from phenomenological model and microscopic appr…
Ab initio study of Curie temperatures of diluted III-V magnetic semiconductors
J. Kudrnovsky, I. Turek, V. Drchal +3
The electronic structure of diluted (Ga,Mn)As magnetic semiconductors in the presence of As-antisites and magnetic disorder is studied within the framework of the local spin densit…
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…
Correlated Doping in Semiconductors: The Role of Donors in III-V Diluted Magnetic Semiconductors
J. Masek, I. Turek, V. Drchal +2
We investigate the compositional dependence of the total energy of the mixed crystals (Ga,Mn)As co-doped with As, Sn, and Zn. Using the ab initio LMTO-CPA method we find a correlat…
