Resolving the exciton Mott transition on the nanoscale
In collaboration with the group of Ermin Malic (University of Marburg), we used ultrafast near-field microscopy to study the Mott transition of strongly-bound excitons in an atomically thin heterostructure of WSe2, unveiling pronounced nanoscale modulation in the dynamics of the transition. These findings underscore how nanoscale disorder plays a pivotal role in the dynamics of many-body phase transitions within a broad range of van der Waals materials.
The results have been published in Nano Letters.
