Excitons in two-dimensional transition metal dichalcogenide monolayers (2D-TMDs) are of essential importance due to their key involvement 2D-TMD-based applications. For instance, exciton dissociation and radiative recombination indispensible processes photovoltaic light-emitting devices, respectively. These two depend drastically on the photogeneration efficiency lifetime excitons. Here, we incorporate femtosecond pump-probe spectroscopy investigate ultrafast dynamics formation decay a...
Two-dimensional transition metal dichalcogenides (2D-TMDs) hold a great potential to platform future flexible optoelectronics. The beating hearts of these materials are their excitons known as XA and XB, which arise from transitions between spin-orbit split (SOS) levels in the conduction valence bands at K-point. functionality 2D-TMD-based devices is determined by dynamics excitons. One most consequential channels exciton decay on device defect-assisted recombination (DAR). Here, we employ...
Femtosecond transient absorption measurements indicate that the transfer of plasmonic electrons from gold nanospheres to methylene blue molecular adsorbates happens on a sub-50 fs time-scale.
