21.10.2021 Rapid exciton dynamics in MoS2 bilayers (published in PRL)

In a joint experiment-theory study with the groups of Elaine Li (University of Texas), Ulrike Woggon and Andreas Knorr (TU Berlin), we have revealed a much faster exciton dynamics in MoS2 bilayers compared to the monolayer case. This is traced back to an efficient intervalley exciton-phonon scattering involving momentum-dark exciton states. Our work was published in Physical Review Letters.
