Spin-polarization and resonant states in electronic conduction through a correlated magnetic layer
Andreas Weh, Wilhelm H. Appelt, Andreas Östlin +2
The transmission through a magnetic layer of correlated electrons sandwiched between non-interacting normal-metal leads is studied within model calculations. We consider the linear…
Charge and heat transport through quantum dots with local and correlated-hopping interactions
Ulrich Eckern, Karol I. Wysokiński
The transport properties of junctions composed of a central region tunnel-coupled to external electrodes are frequently studied within the single-impurity Anderson model with Hubba…
Electronic and optical properties of metal-doped TiO nanotubes: Spintronic and photocatalytic applications
Mohamed M. Fadlallah, Ulrich Eckern
Due to their characteristic geometry, TiO nanotubes (TNTs), suitably doped by metal-substitution to enhance their photocatalytic properties, have a high potential for applicati…
Spectral properties of heterostructures containing half-metallic ferromagnets in the presence of local many-body correlations
A. Weh, J. Otsuki, H. Schnait +4
In this work, we investigate models for bulk, bi- and multilayers containing half-metallic ferromagnets (HMFs), at zero and at finite temperature, in order to elucidate the effects…
Multi-terminal far-from-equilibrium thermoelectric nano-devices in the Kondo regime
Ulrich Eckern, Karol I. Wysokiński
The quest for good thermoelectric materials and/or high-efficiency thermoelectric devices is of primary importance from theoretical and practical points of view. Low-dimensional st…
Spin-charge conversion in NiMnSb Heusler alloy films
Zhenchao Wen, Zhiyong Qiu, Sebastian Tolle +7
Half-metallic Heusler alloys are attracting considerable attention because of their unique half-metallic band structures which exhibit high spin polarization and yield huge magneto…
