Theory of the coupling of transition metal impurities with free carriers in ZnO
Anna Ciechan, Piotr Bogusławski
The exchange coupling between the spins of band carriers and of transition metal (TM) dopants ranging from Ti to Cu in ZnO is studied within the density functional theory.…
Green luminescence and calculated optical properties of Cu ions in ZnO
O. Volnianska, P. Boguslawski
There are two characteristic optical transitions associated with Cu ions in ZnO, the 0.72 eV infrared and the 2.86 eV structured green luminescence (SGL). While the former is unamb…
Transition metal ions in ZnO: effects of intrashell Coulomb repulsion on electronic properties
A. Ciechan, P. Bogusławski
Electronic structure of the transition metal (TM) dopants in ZnO is calculated by first principles approach. Analysis of the results is focused on the properties determined by the…
Alloy broadening of the transition to the non-trivial topological phase of Pb_{1-x}Sn_{x}Te
A. Lusakowski, P. Boguslawski, T. Story
Transition between the topologically trivial and non-trivial phase of Pb_{1-x}Sn_{x}Te alloy is driven by the increasing content of Sn, or by the hydrostatic pressure for $x<0.…
Calculated optical properties of Co in ZnO: internal and ionization transitions
A. Ciechan, P. Bogusławski
Previous luminescence and absorption experiments in Co-doped ZnO revealed two ionization and one intrashell transition of electrons. Those optical properties…
