Delafossite CuAlO 2 is a prototype p-type transparent conducting oxide. We have performed ab initio total energy calculation on native point defects to investigate the origin of p-type conductivity in 'undoped' CuAlO 2 . Copper-and oxygen-related defects, such as vacancies, interstitials, and antisi

Using a molecular cluster with 71 atoms, we studied the electronic and structural properties of nitrogen vacancy, boron antisite, and oxygen in cubic boron nitride through an ab initio HartreeαFock calculation. We found that all defects introduce a deep state above the middle-energy gap. These defec
We present the first detection of native defects in ZnSiP 2 . Similar to p-type ZnGeP 2 , the EPR spectra of the zinc vacancy V Γ Zn ; the phosphorus vacancy V 0 P ; as well as of group IV anti-site Si ΓΎ Zn Γ°Ge ΓΎ Zn Γ could be proved. The influence of the group IV-ions on the bonding behavior for th
