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....
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 ...
Crystalline semiconductors are integral components of today’s electronic devices and are thus of fundamental significance to science and technology alike. A detailed understanding of their optical response, stemming from the complex collective dynamics of their periodically arranged charge carriers, is cruci...
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 ...
