Magneto-optical Properties of Reduced Titania Probed by First-principles Calculations: Polarons
C. Echeverria-Arrondo, H. Raebiger, J. Perez-Conde +2
The magneto-optical properties of titanium dioxide systems are related to the presence of impurity states in the band gap due to oxygen vacancies. To understand about the interplay…
Resistive Switching in Nanodevices
Hannes Raebiger, Antonio Claudio M. Padilha, Alexandre R. Rocha +1
Passing current at given threshold voltages through a metal/insulator/metal sandwich structure device may change its resistive state. Such resistive switching is unique to nanoscal…
Molecular Motion on Semiconductor Surface via Tip-enhanced Multiple Excitation
Tatsuya Momose, Ken-ichi Shudo, Hannes Raebiger +5
In a low-temperature study with a scanning tunneling microscope (STM), the irreducible lateral motion of a CO molecule adsorbed on a Si(001) surface showed a hyperlinear dependence…
Crossover of high and low spin states in transition metal complexes
Hannes Raebiger, Shuhei Fukutomi, Hiroshi Yasuhara
The stability of high vs. low spin states of transition metal complexes has been interpreted by ligand field theory, which is a perturbation theory of the electron-electron interac…
Diffusion and clustering of substitutional Mn in (Ga,Mn)As
Hannes Raebiger, Maria Ganchenkova, Juhani von Boehm
The Ga vacancy mediated microstructure evolution of (Ga,Mn)As during growth and post-growth annealing is studied using a multi-scale approach. The migration barriers for the Ga vac…
High Curie temperatures in (Ga,Mn)N from Mn clustering
Teemu Hynninen, Hannes Raebiger, Andres Ayuela +1
The effect of microscopic Mn cluster distribution on the Curie temperature (Tc) is studied using density-functional calculations. We find that the calculated Tc depends crucially o…
