The progression of carrier confinement from quantum wells to quantum dots has received
considerable interests because of the potential to improve the semiconductor laser …

Atomically thin transition metal dichalcogenides are direct-gap semiconductors with strong
light–matter and Coulomb interactions. The latter accounts for tightly bound excitons, which …

Nonequilibrium carrier dynamics in single exfoliated graphene layers on muscovite
substrates are studied by ultrafast optical pump-probe spectroscopy and compared with …

Excitons dominate the optical properties of monolayer transition metal dichalcogenides
(TMDs). Besides optically accessible bright exciton states, TMDs exhibit also a multitude 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 …

We investigate the relaxation kinetics of optically excited charge carriers in graphene
focusing on the time-, momentum-, and angle-resolved interplay between carrier-carrier and …

In single-layer (1L) transition metal dichalcogenides, the reduced Coulomb screening
results in strongly bound excitons which dominate the linear and the nonlinear optical …

The remarkably strong Coulomb interaction in atomically thin transition metal
dichalcogenides (TMDs) results in an extraordinarily rich many-particle physics including the …

Monolayers of semiconducting transition metal dichalcogenides hold the promise for a new
paradigm in electronics by exploiting the valley degree of freedom in addition to charge and …

Enhanced Coulomb interactions in monolayer transition metal dichalcogenides cause tightly
bound electron-hole pairs (excitons) that dominate their linear and nonlinear optical …
