Dark trions govern the temperature-dependent optical absorption and emission of doped atomically thin semiconductors

Ashish Arora, Nils Kolja Wessling, Thorsten Deilmann +7

We perform absorption and photoluminescence spectroscopy of trions in hBN-encapsulated WSe${}_2$, WS${}_2$, MoSe${}_2$, and MoS${}_2$ monolayers, depending on temperature. The different tr…
