First-principles study of ferromagnetism in epitaxial Si-Mn thin films on Si(001).
Density-functional theory calculations are employed to investigate both the epitaxial growth and the magnetic properties of thin Mn and MnSi films on Si(001). For single Mn adatoms, we find a preference for the second-layer interstitial site. While a monolayer Mn film is energetically unfavorable, a capping-Si layer significantly enhances the thermodynamic stability and induces a change from an...
متن کاملStrain-modulated ferromagnetism and band gap of Mn doped Bi2Se3
The quantized anomalous Hall effect (QAHE) have been theoretically predicted and experimentally confirmed in magnetic topological insulators (TI), but dissipative channels resulted by small-size band gap and weak ferromagnetism make QAHE be measured only at extremely low temperature (<0.1 K). Through density functional theory calculations, we systemically study of the magnetic properties and el...

In this paper, the structural parameters, energy bands structure, density ofstates and charge density of HgSe in the Zincblende(B3) phase have been investigated.The calculations have been performed using the Pseudopotential method in theframework of density functional theory (DFT) by Quantum Espresso package. Theresults for the electronic density of states (DOS) show tha...
متن کاملFirst-Principles Study of Magnetic Properties of 3dTransition Metals Doped in ZnO Nanowires
The defect formation energies of transition metals (Cr, Fe, and Ni) doped in the pseudo-H passivated ZnO nanowires and bulk are systematically investigated using first-principles methods. The general chemical trends of the nanowires are similar to those of the bulk. We also show that the formation energy increases as the diameter of the nanowire decreases, indicating that the doping of magnetic...
متن کاملFerromagnetism in Nitrogen Doped Magnesium Oxide: a First Principle Study
The formation of magnetic moment in the p-orbital doped semiconductors is named d0 magnetism, where the ion without partially filled d states is found to be responsible for the magnetism. To study origin of magnetism in such p-orbital doped semiconductors, we report a theoretical investigation of electronic and magnetic properties of N doped MgO, with and without an oxygen vacancy. The first pr...
