Electronic structure of Zn, Cu and Ni impurities in germanium

Alexandra Sarabando de Carvalho

We present a density functional modelling study of Zn, Cu and Ni impurities in hydrogen-terminated germanium clusters. Their electronic structure is investigated in detail, especially their Jahn-Teller instabilities and electrical levels. Interstitial and ...

Intrinsic defect complexes in CdTe and ZnTe

Alexandra Sarabando de Carvalho

Radiation defects in CdTe and ZnTe are modeled from first principles. The most important intrinsic defects resulting from cation evaporation or displacement are cation vacancies and tellurium anti-sites, electrically active defects characterized by a low f ...

Cation-site intrinsic defects in Zn-doped CdTe

Nava Setter, Alexander Tagantsev, Alexandra Sarabando de Carvalho

The properties of the cation vacancy and the Te antisite, two dominant defects in CdTe and Cd1-xZnxTe alloys grown in Te-rich conditions, are examined using first-principles calculations. First, the structure, electronic levels, and migration paths of V-Cd ...

Li-related defects in ZnO : hybrid functional calculations

Nava Setter, Alfredo Pasquarello, Alexander Tagantsev, Audrius Alkauskas, Alexandra Sarabando de Carvalho

Hybrid density functional calculations are used to model substitutional lithium (LiZn) and interstitial lithium (Lii) defects in ZnO. The calculated transition levels and formation energies are compared to those obtained using a semilocal density functiona ...

Intrinsic defects in CdTe and CdZnTe alloys

Nava Setter, Alexander Tagantsev, Alexandra Sarabando de Carvalho

The Cd vacancy (VCd) and Te anti-site (TeCd) are two dominant defects in CdTe and CdZnTe alloys grown in Te-rich conditions. We examine the properties of these two intrinsic defects in Cd1-xZnxTe alloys with x

The self-interstitial in silicon and germanium

Alexandra Sarabando de Carvalho

Low temperature irradiation experiments show a remarkable contrast between Si and Ge. suggesting that the behavior of self-interstitials and vacancies is very different in the two materials. The present paper reviews theoretical and experimental investigat ...
