- The lecture series will be given as an asynchronous online class, i.e. in the form of videos with recorded learning units that will be available via the FAU vide portal. Complementary slides and written summaries of the lectures will be available online via the studon portal. The exercise class will be held live online.
This course will discuss the basic photophysical processes involved in and following the optical excitation of materials. Experimental techniques will be introduced to characterize these processes, which involve the optical absorption of light, the subsequent energetic carrier relaxation, phototransport, and carrier recombination. The functionality and performance of a large number of optoelectronic components, such as solar cell absorbers, photodetectors, or emitter materials for light-emitting diodes, rely on different combinations of these steps. While they can, in principle, be observed in a large variety of condensed-matter systems, their dynamics differ strongly between bulk direct and indirect band semiconductors, (quantum) confined systems, or materials with strong carrier localization, which can arise from exciton or polaron formation. The spectroscopic and time-resolved techniques, which are commonly applied to characterize the responses of these different systems to photoexcitation, will be introduced. These include both optical and electron spectroscopy techniques.
