Metal-insulator transition in the In/Si(111) surface
Sampsa Riikonen, Andres Ayuela, Daniel Sanchez-Portal
The metal-insulator transition observed in the In/Si(111)-4x1 reconstruction is studied by means of ab initio calculations of a simplified model of the surface. Different surface b…
High Curie temperatures in (Ga,Mn)N from Mn clustering
Teemu Hynninen, Hannes Raebiger, Andres Ayuela +1
The effect of microscopic Mn cluster distribution on the Curie temperature (Tc) is studied using density-functional calculations. We find that the calculated Tc depends crucially o…
Electronic and magnetic properties of substitutional Mn clusters in (Ga,Mn)As
H. Raebiger, A. Ayuela, J. von Boehm
The magnetization and hole distribution of Mn clusters in (Ga,Mn)As are investigated by all-electron total energy calculations using the projector augmented wave method within the…
