Nanosystems 2 (Physics of Nano-Optics)

This module gives an introductory in the optical properties of organic and inorganic nanosystems. Starting with an idealized two-level system, the optical properties of 3D, 2D and 0D electronic systems are introduced. A particular emphasis will be put on the optical control of the spin states of the charge carriers. In addition, the fluorescence of organic nanosystems will be introduced and plasmonic properties of metal nanosystems such as nanoparticles are discussed. Furthermore, heat, charge, and energy transfer processes after an optical excitation will be explained. Corresponding sensing application of nanoscale systems are introduced. A further emphasis is put on the optical and optoelectronic properties of topical material systems, such as graphene, topological insulators, single molecules and proteins, and carbon nanotubes.

After a successful participation of the module, the student is able to:
1) discuss the impact of spatial confinement on the optical properties of nanosystems.
3) explain and specify the fluorescence of nanosystems.
4) explain surface plasmon polaritons at metal interfaces.
5) explain and specify plasmon resonances in nanoparticles.
6) explain heat, charge, and energy transfer processes in nanoscale circuits.
7) differentiate between the different optically induced current contributions in nanoscale systems.

There are no access requirements beyond the ones for the master study.

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.
