Strong-correlation effects in Born effective charges
Alessio Filippetti, Nicola A. Spaldin
Large values of Born effective charges are generally considered as reliable indicators of the genuine tendency of an insulator towards ferroelectric instability. However, these qua…
A self-interaction corrected pseudopotential scheme for magnetic and strongly-correlated systems
Alessio Filippetti, Nicola Spaldin
Local-spin-density functional calculations may be affected by severe errors when applied to the study of magnetic and strongly-correlated materials. Some of these faults can be tra…
Self-interaction effects in (Ga,Mn)As and (Ga,Mn)N
Alessio Filippetti, Nicola A. Spaldin, Stefano Sanvito
The electronic structures of Mn-doped zincblende GaAs and wurtzite GaN are calculated using both standard local-density functional theory (LSDA), and a novel pseudopotential self-i…
