The trigonal structure as a reference to access the spontaneous polarization of wurtzite crystals
Abdesamed Benbedra, Said Meskine, Abdelkader Boukortt +3
The spontaneous polarization of wurtzite III-V nitrides XN (X=Al, Ga, In) and II-VI oxides YO (Y=Be, Zn) is investigated via first-principles computational methods. The modern trea…

Exchange coupling and Mn valency in GaN doped with Mn and co-doped with Mg
Mostefa Djermouni, Ali Zaoui, Roland Hayn +1
We study 1 or 2 neighboring Mn impurities, as well as complexes of 1 Mn and 1 or 2 Mg ions in a 64 atoms supercell of GaN by means of density functional calculations. Taking into a…

Electronic structure and Jahn-Teller effect in GaN:Mn and ZnS:Cr
F. Virot, R. Hayn, A. Boukortt
We present an ab-initio and analytical study of the Jahn-Teller effect in two diluted magnetic semiconductors (DMS) with d4 impurities, namely Mn-doped GaN and Cr-doped ZnS. We sho…
