Recent advances in moiré superlattices and moiré excitons, such as quantum emission
arrays, low-energy flat bands, and Mott insulators, have rapidly attracted attention in the …

An overall understanding of the carrier dynamics in two-dimensional transition metal
dichalcogenides (TMDs) is necessary to improve the quantum efficiencies and …

The strong light-matter interaction and the valley selective optical selection rules make
monolayer (ML) MoS 2 an exciting 2D material for fundamental physics and optoelectronics …

Recent optical studies of monolayer transition-metal dichalcogenides have demonstrated
that their excitonic absorption feature splits into two widely separated peaks at finite carrier …

Named after the two‐faced Roman god of transitions, transition metal dichalcogenide (TMD)
Janus monolayers have two different chalcogen surfaces, inherently breaking the out‐of …

We present low-temperature magneto-photoluminescence experiments which demonstrate
the brightening of dark excitons by an in-plane magnetic field B applied to monolayers of …

We demonstrate the reduction of the inhomogeneous linewidth of the free excitons in
atomically thin transition metal dichalcogenides (TMDCs) MoSe2, WSe2 and MoS2 by …

Recently, it has been demonstrated that the absorption of moderately doped two-
dimensional semiconductors can be described in terms of exciton polarons. In this scenario …

The direct gap interband transitions in transition metal dichalcogenide monolayers are
governed by chiral optical selection rules. Determined by laser helicity, optical transitions in …

We present a comprehensive optical study of thin flakes of tungsten disulfide (WS2) with
thickness ranging from mono-to octalayer and in the bulk limit. It is shown that the optical …
