Description: |
Through patterning on the nanometer scale, the electrical, magnetic and optical properties of metals, insulators, and semiconductors can be profoundly altered. This opens up the possibility to tailor the characteristics of novel devices. In this course, the different phenomena will be discussed, which will lead to these size effects.
Starting from the bulk solid state properties of metals, insulators, and semiconductors, the following topics will be covered:
Layered structures: dielectric mirrors, semiconductor heterostructures, magnetic layers and interfaces, magnetic sensors (GMR, TMR). One-dimensional systems: carbon nanotubes, ballistic transport, quantized conductance. Nanoparticles and quantum dots: Coulomb blockade, single electron transistor, quantum dot lasers.
Furthermore, seminar-style student talks will strengthen presentation and teamwork skills. |
