trionpiezoelectricityBy exploiting the very recent discovery of the piezoelectricity in odd-numbered layers of two-dimensional molybdenum disulfide (MoS2), we show the possibility of reversibly tuning the photoluminescence of single and odd-numbered multilayered MoS2 using high frequency sound wave coupling...

The heterostructure of monolayer transition metal dichalcogenides (TMDCs) provides a unique platform to manipulate exciton dynamics. The ultrafast carrier transfer across the van der Waals interface of the TMDC hetero-bilayer can efficiently separate electrons and holes in the intralayer excitons with a ...
In this work, MoS2 2D-QDs were grown on SiO2/Si by chemical vapor deposition and their exciton and trion photoluminescence were studied in comparison to MoS2 flakes. The 2D-QDs have a round-like shape with the average lateral size of 40 nm and trTlayer structure. Both the structures show ...
the valley evolution dynamics of trions (T) and excitons (X), respectively. The co-polarized data (Co) reflects the decay processes within the excitation valley, while the cross-polarization signal (Cr) depicts the population redistribution dynamics between K and K’ valleys.c,dNear-resonant hel...
This allows to evaluate the spin-orbit splitting, quenching activation energy, trion effective size and other important parameters. These new findings are useful for the potential applications of few-layer MoS2 in nano-optoelectronics involving external modulation of optical properties....

Plasmon-trion and plasmon-exciton resonance energy transfer from a single plasmonic nanoparticle to monolayer MoS2. Nanoscale 2017, 9, 13947-13955, doi:10.1039/C7NR03909C.Wang M, Li W, Scarabelli L, Rajeeva B B, Terrones M, Liz-Marzan L M, Akinwande D, Zheng Y, Plasmon-trion and ...
In this study, the PL enhancement of 2D MoS 2 decorated with Au nanorods (NRs) and nanospheres (NSs) at room temperature is investigated, focusing in particular on the effect of the nonspherical shape of NRs. To have a proper comparison, both nanoparticles have very similar diameters of 13...
