Content, Learning Outcome and Preconditions
This module gives an overview over magnetism and correlation phenomena in semiconductor and oxide heterostructures. After an introduction to the basics of magnetism electronic band structures with special regard to spin-orbit coupling are discussed. In the following, magnetic quantum oscillations in two-dimensional electron systems are treated. The impact of the spin degree of freedom, of the many-body interaction and of the dimensionality of the charge carrier systems on the energy spectrum in a magnetic field is considered and explained within theoretical models. Relevant aspects of semiconductor spintronics like injection and detection of spin-polarized currents, spin coherence and spin relaxation, optical spin orientation and electrical manipulation of spin states via spin-orbit coupling are discussed. The emergence of strongly correlated two-dimensional electron systems in oxide heterostructures is reviewed and potential novel functionalities are discussed.
After successful participation in this module the student is able to:
- describe the impact of spin-orbit coupling on the electronic states in semiconductors;
- comprehend and explain orbital and spin-related effects on the magnetism of low-dimensional electron systems;
- evaluate the influence of disorder, temperature, many-body effects, choice of material and dimensionality on the electronic spectrum;
- name and explain basic physical aspects of modern semiconductor spintronics like electrical and optical spin injection, manipulation and detection;
- differentiate between different spin-dependent scattering mechanisms;
- understand and explain properties of magnetic semiconductors;
- comment on the emergence of strongly correlated electron systems at oxide interfaces and sketch potential novel functionalities;
- develop a scientific theme with guidance, create a presentation and give a talk as well as judge presentation techniques and apply them.
Keine Vorkenntnisse nötig, die über die Zulassungsvoraussetzungen zum Masterstudium hinausgehen.
