Optimally Designed Digitally-Doped Mn:GaAs
J. L. Xu, M. van Schilfgaarde
We use the ab initio local-density approximation (LDA) to study of exchange interactions and Tc of Ga1−xMnxAs grown in digitally doped structures. We analyze the crystallogra…

Optimizing Tc in the (Mn,Cr,Ga)As and (Mn,Ga)(As,P) Ternary Alloys
J. L. Xu, M. van Schilfgaarde
We explore two possible ways to enhance the critical temperature in the dilute magnetic semiconductor MnGaAs. Within the context of the double-exchange and…

Role of Disorder in Mn:GaAs, Cr:GaAs, and Cr:GaN
J. L. Xu, M. van Schilfgaarde, G. D. Samolyuk
We present calculations of magnetic exchange interactions and critical temperature T_c in Mn:GaAs, Cr:GaAs and Cr:GaN. The local spin density approximation is combined with a linea…
