Sub-100 fs Formation of Dark Excitons in Monolayer WS₂.

Nevertheless, compared to the interior, at the edges there is a clear trend of a lower sub-100 fs photoemission signal accompanied by larger photoemission on picosecond time scale (with photoemission intensity unchanged at subpicosecond delays) similar to what was observed in fluence-dependent measurements.
