Strongly bound excitons confined in two-dimensional (2D) semiconductors are dipoles with
a perfect in-plane orientation. In a vertical stack of semiconducting 2D crystals, such in-plane …

Atomically thin transition metal dichalcogenides can be stacked to van der Waals
heterostructures enabling the design of new materials with tailored properties. The strong …

Two-dimensional (2D) transition-metal dichalcogenides (TMDs) have shown great potential
in ultrathin and flexible optoelectronic and photonics devices. Besides emissive bright …

Quasi-two-dimensional (2D) organic–inorganic hybrid perovskite is a re-emerging material
with strongly excitonic absorption and emission properties that are attractive for photonics …

The optical spectra of two-dimensional (2D) materials exhibit sharp absorption peaks that
are commonly identified with exciton and trions (or charged excitons). In this paper, we show …

We present a many-body theory of exciton-trion polaritons (ETPs) in doped two-dimensional
semiconductor materials. ETPs are robust coherent hybrid excitations involving excitons …

Abstract Two‐dimensional (2D) layered materials have been in the spotlight of scientists'
interest for more than a decade. The inherently weak interaction between the layers in 2D …

The broken mirror symmetry of two-dimensional (2D) Janus materials brings novel quantum
properties and various application prospects. Particularly, when stacking into …

Optical absorption and emission spectra of doped two-dimensional (2D) materials exhibit
sharp peaks that are often mistakenly identified with pure excitons and pure trions (or …

The strong light–matter interaction in monolayer transition metal dichalcogenides (TMDs) is
promising for nanoscale optoelectronics with their direct band gap nature and the ultrafast …
