Time-dependent absorption spectra are analyzed by tracking the line width broadening, bleaching, and energy shift of the main exciton resonance as a function of time delay after the excitation. Two main sources for the pump-induced changes of the optical response are identified. Specifically, we find an interplay between modifications induced by many-body interactions from photoexcited carriers and by the subsequent transfer of the excitation to the phonon system followed by cooling of the material through the heat transfer to the substrate.","lang":"eng"}],"publication":"Nano Letters","doi":"10.1021/acs.nanolett.6b03513","author":[{"first_name":"Claudia","full_name":"Ruppert, Claudia","last_name":"Ruppert"},{"last_name":"Chernikov","full_name":"Chernikov, Alexey","first_name":"Alexey"},{"last_name":"Hill","full_name":"Hill, Heather M.","first_name":"Heather M."},{"first_name":"Albert F.","full_name":"Rigosi, Albert F.","last_name":"Rigosi"},{"full_name":"Heinz, Tony F.","last_name":"Heinz","first_name":"Tony F."}],"volume":17,"date_updated":"2022-01-06T07:03:11Z","citation":{"mla":"Ruppert, Claudia, et al. “The Role of Electronic and Phononic Excitation in the Optical Response of Monolayer WS2 after Ultrafast Excitation.” <i>Nano Letters</i>, vol. 17, no. 2, American Chemical Society (ACS), 2017, pp. 644–51, doi:<a href=\"https://doi.org/10.1021/acs.nanolett.6b03513\">10.1021/acs.nanolett.6b03513</a>.","short":"C.
