Abstract

Two-dimensional semiconductors, such as monolayer two-dimensional (2D) transition metal dichalogenides, and their heterostructures have attracted much attention and intensively studied from viewpoint of fundamental physics and optical applications [1-8]. When monolayers with a slight lattice mismatch or small twist angle are stacked, spatially varying atomic registries give rise to the moiré superlattice, which consequently induces a periodic moiré potential landscape. The confined excitonic states in the moiré potential (moirés exciton) provide the platform for studying the advanced quantum optics. Here, I will present about the selected recent research topics toward advanced quantum optics in 2D materials and artificial van der Waals semiconducting heterostructures [4,5].
