Influence of quantum confinement on the ferromagnetism of (Ga,Mn)As diluted magnetic semiconductor
Sameer Sapra, D. D. Sarma, S. Sanvito +1
We investigate the effect of quantum confinement on the ferromagnetism of diluted magnetic semiconductor GaMnAs using a combination of tight-binding and density functio…
Density functional calculations for III-V diluted ferromagnetic semiconductors: A Review
S. Sanvito, G. Theurich, N. A. Hill
In this paper we review the latest achievements of density functional theory in understanding the physics of diluted magnetic semiconductors. We focus on transition metal doped III…
Ab-initio transport theory for digital ferromagnetic heterostructures
Stefano Sanvito, Nicola A. Hill
MnAs/GaAs superlattices, made by -doping GaAs with Mn, are known as digital ferromagnetic heterostructures. Here we present a theoretical density functional study of the electro…
Do As antisites destroy the ferromagnetism of (Ga,Mn)As?
Stefano Sanvito, Nicola A. Hill
The effect of the inclusion of As antisites in the diluted magnetic semiconductor (Ga,Mn)As is studied within density functional theory in the local spin density approximation. In…
First principles study of the origin and nature of ferromagnetism in (Ga,Mn)As
Stefano Sanvito, Pablo Ordejon, Nicola A. Hill
The properties of diluted GaMnAs are calculated for a wide range of Mn concentrations within the local spin density approximation of density functional theory. Mülliken…
Spin-Orbit Coupling in the ab initio Pseudopotential Framework
G. Theurich, N. A. Hill
We describe the implementation of total angular momentum dependent pseudopotentials in a plane wave formulation of density functional theory. Our approach thus goes beyond the scal…
