Abstract:
The energy transfer mechanism leading to highly efficient nonradiative energy transfer (NRET) from quantum dots (QDs) to monolayer MoS2 devices has been investigated via a spectral dependence study. The spectral dependence of the NRET from three spectrally separated QD ensembles to monolayer MoS2 devices reveals that the trends in NRET rates follow the trends in the spectral overlap between the QD emission and MoS2 absorption spectra, thus verifying that the mechanism for the energy transfer is Förster-type NRET. Furthermore, the dependence of the photocurrent enhancement on the MoS2 film properties is also explored.
