A van der Waals heterostructure built from atomically thin semiconducting transition metal
dichalcogenides (TMDs) enables the formation of excitons from electrons and holes in …

Monolayer group-VI transition metal dichalcogenides have recently emerged as
semiconducting alternatives to graphene in which the true two-dimensionality is expected to …

Theoretical and experimental results on excitonic effects in monomolecular layers of
transition metal dichalcogenides are reviewed. These two-dimensional semiconductors …

Strong Coulomb interaction in atomically thin transition metal dichalcogenides makes these
systems particularly promising for studies of excitonic physics. Of special interest are the …

We investigates exciton-exciton annihilation (EEA) in tungsten disulfide (WS 2) monolayers
encapsulated by hexagonal boron nitride (hBN). It is revealed that decay signals observed …

The emission and absorption spectra of quantum wells containing electron or hole gas are
reviewed. We show that trions, also known as charged excitons, play a dominant role in …

Embedding a WS 2 monolayer in flakes of hexagonal boron nitride allowed us to resolve
and study the photoluminescence response due to both singlet and triplet states of …

We experimentally demonstrate dressing of the excited exciton states by a continuously
tunable Fermi sea of free charge carriers in a monolayer semiconductor. It represents an …

Near-infrared emission from semiconducting single-walled carbon nanotubes (SWNTs)
usually results from radiative relaxation of excitons. By binding an additional electron or hole …

The electronic and structural properties of excitons and trions in monolayer transition metal
dichalcogenides are investigated using both a multiband and a single-band model. In the …
