Objectives
1 To experimentally probe the exciton-exciton interactions in two-dimensional atomic crystals including multilayers and monolayers of transition metal dichalcogenides and monochalcogenides. The nature of exciton-exciton interactions in 2D system is to be examined at various conditions. 2 To explore the phenomena associated with excitons, from biexcitons to electron-hole droplets in 2D atomic crystals. These many-body phenomena have been intensively studied in quasi-2D semiconductors for decades. With the emergence of 2D atomic crystals, weak Coulomb screening, strong spatial confinement and extra degrees of freedom make atomic 2D crystals an interesting platform to explore many-body effect in 2D system.
