- Experimental physics of modern materials: Photophysics
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.Contents:
band-to-band transitions in direct and indirect semiconductors
electron-hole interaction and excitons, especially in low-dimensional systems
electron-phonon coupling and polaron formation
phototransport of delocalized carriers and localized excitations
radiative and nonradiative recombination
introduction to solar cells, photodetectors, and light-emitting diodes
the Shockley-Queisser efficiency limit in solar cells
concepts for next-generation photovoltaics beyond the Shockley-Queisser limit
