Comparison of density functionals for nitrogen impurities in ZnO
Sung Sakong, Johann Gutjahr, Peter Kratzer
Hybrid functionals and empirical correction schemes are compared to conventional semi-local density functional theory (DFT) calculations in order to assess the predictive power of…

As vacancies, Ga antisites and Au impurities in Zincblende and Wurtzite GaAs nanowire segments from first principles
Yaojun A. Du, Sung Sakong, Peter Kratzer
In this paper some specific issues related to point defects in GaAs nanowires are addressed with the help of density functional theory calculations. These issues mainly arise from…

Anisotropic ferromagnetism in carbon doped zinc oxide from first-principles studies
Sanjeev K. Nayak, Markus E. Gruner, Sung Sakong +4
A density functional theory study of substitutional carbon impurities in ZnO has been performed, using both the generalized gradient approximation (GGA) and a hybrid functional (HS…
