Since the discovery of graphene in 2004, a plethora of two-dimensional (2D) quantum materials
has been investigated. Among 2D semiconductors, transition metal dichalcogenides have been of
particular interest due to their direct band gap in the monolayer, large exciton binding energies,
and strong light-matter interaction. Within the class of 2D magnets, air-stable CrSBr stands out as
an antiferromagnetic semiconductor with a high Néel temperature and excitons coupled to the
magnetic order. In this talk, I will present three of my postdoctoral projects. First, I will introduce
moiré physics and show large-area atomic reconstruction in MoSe2-WSe2 heterobilayers [1]. The
second part will be about doping-control of excitons and magnetism in few-layer magnetic
semiconductor CrSBr [2]. Lastly, I will show different realizations of polariton microcavities with
monolayers of transition metal dichalcogenides [3].
