TL;DR: Measurements of the coherent and incoherent exciton dynamics on the 100 fs to 10 ns time scale are reported, determining dephasing and density decay rates in these NCs.

TL;DR: It is found that the exciton dynamics is governed by microscopic disorder on top of the ideal crystal properties, which provides stable monolayer samples with low disorder, avoiding surface contaminations and the resulting exciton broadening and modifications of the dynamics.

TL;DR: In this paper, the authors measured the directional emission of the circularly polarized transitions in a magnetic field into counter-propagating guided modes, to deduce the mode circularity at the quantum dot sites.

TL;DR: In this paper, the exciton and trion density dynamics in a single layer of MoSe2, resonantly excited and probed using three-pulse four-wave mixing (FWM), at temperatures from 300 K to 77 K were investigated.

TL;DR: It is argued that excitons in InP-based QDs are nearly isotropic because the particular ratio of light and heavy hole masses in In P makes the exciton fine structure insensitive to shape anisotropy.
