Title of Talk: Probing excitons, polarons and trions as quasiparticles in one-dimensional single-walled carbon nanotubes

Abstract: I will give a brief introduction to the photophysics of single-walled carbon nanotubes and how their quasi one-dimensional structure enables the
observation of quasiparticles such as excitons, polarons and trions at room temperature by simple optical absorption and photoluminescence spectroscopy
in the near-infrared. A special focus will be the dependence of these optical properties and of the formation and decay of excitons and trions on
charge carrier density, which can be tuned widely by chemical, electrochemical and electrostatic doping.

Venue (HYBRID-EVENT): Goldene Box, Physikalisches Institut, INF 226, 69120 Heidelberg AND all talks will also be streamed via the permanent Zoom-link:

The main idea of the CRC 1225 Lunch Seminars is to bring together all scientists involved in our collaboration on a regular basis to allow exchange and discussion even outside one’s own research topics. We therefore invite all PIs and working group members of the CRC 1225 ISOQUANT to participate in the Lunch Seminars and to use this opportunity for getting to know each other, fruitful discussions and valuable exchange.
