Localisation-to-delocalisation transition of moiré excitons in WSe${}_2$/MoSe${}_2$ heterostructures

Elena Blundo, Federico Tuzi, Salvatore Cianci +12

Moiré excitons (MXs) are electron-hole pairs localised by the periodic (moiré) potential forming in two-dimensional heterostructures (HSs). MXs can be exploited, $e.g.$, for creati…
