Coexistence of Antiferromagnetic Cubic and Ferromagnetic Tetragonal Polymorphs in Epitaxial CuMnSb
Anna Ciechan, Piotr Dluzewski, Slawomir Kret +7
High-resolution transmission electron microscopy and superconducting quantum interference device magnetometry shows that epitaxial CuMnSb films exhibit a coexistence of two magneti…
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.…
Electronic properties of BiSe dopped by transition metal (Mn, Fe, Co, or Ni) ions
Andrzej Ptok, Konrad Jerzy Kapcia, Anna Ciechan
Topological insulators are characterized by the existence of band inversion and the possibility of the realization of surface states. Doping with a magnetic atom, which is a source…
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…
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…
