Ultrafast Photoelectron Spectroscopy - How to Make Movies of Elementary Electronic Processes
Ultrafast Photoelectron Spectroscopy - How to Make Movies of Elementary Electronic Processes
How does functionality in quantum devices emerge? The answer lies in the numerous elementary processes, the interactions and correlations of (quasi-)particles that happen on timescales of femtoseconds. Thorough understanding of these processes can eventually lead to more efficient OLEDs, faster microprocessors, and other functional materials. A complex, but highly insightful method to access the required spectral and dynamic information in solid state systems is time- and angle-resolved photoemission spectroscopy. This lecture attempts to give an overview on this powerful technique for exploring non-equilibrium properties of matter. This includes discussions of elementary scattering processes, experimental techniques, and latest results on optoelectronic systems and correlated materials.
