Jahn-Teller Distortion and Ferromagnetism in the Dilute Magnetic Semiconductors GaN:Mn

Xuan Luo, Richard M. Martin

Using first-principles total-energy methods, we investigate Jahn-Teller distortions in III-V dilute magnetic semiconductors, GaAs:Mn and GaN:Mn in the cubic zinc blende structure.…

Spin-Orbit Effects in Diluted Magnetic Semiconductors

Byounghak Lee, Xavier Cartoixa, Nandini Trivedi +1

We present a theoretical study of diluted magnetic semiconductors that treats the local sp-d exchange interaction J between the itinerant carriers and the Mn d electrons within a r…

Electron-Phonon Interactions in C $_{28}$ -derived Molecular Solids

Nichols A. Romero, Jeongnim Kim, Richard M. Martin

We present {\it ab initio} density-functional calculations of molecular solids formed from C $_{28}$ -derived closed-shell fullerenes. Solid C $_{28}$ H $_{4}$ is found to bind weakly and…
