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 strain/electronic interplay in ZnO; Stress and temperature dependence of the piezoelectric constants
Nicola A. Hill, Umesh Waghmare
We present a first-principles study of the relationship between stress, temperature and electronic properties in piezoelectric ZnO. Our method is a plane wave pseudopotential imple…
Magnetic stress as a driving force of structural distortions: the case of CrN
Alessio Filippetti, Nicola A. Hill
We show that the observed transition from rocksalt to orthorhombic P symmetry in CrN can be understood in terms of stress anisotropy. Using local spin density functional th…
