Summary
Non-technical Abstract: This work focuses on experimental studies of fundamental optical and electronic properties of structures made of thin layers of semiconductors. A special design of the structures on a length scale of a billionth part of a meter allows the creation of new quasi-particles called indirect excitons. The indirect excitons are unique because they can be cooled down to ultralow temperatures. Furthermore, the indirect excitons are unique because they have long lifetimes and can travel over long distances. In particular, the project address excitonic Bose polarons, which are rec
