Abstract
Owing to outstandingly tunable optoelectronic properties, hybrid materials consisting of atomic scale thickness of two dimensional (2D) transition metal dichalcogenides (TMDs) and one dimensional (1D) nanowires have been attracting steady interests over the last several years. In this research for the first time we report optically probing the interaction between monolayer MoS2 and single-wall carbon nanotube (SWCNT). By using Raman and photoluminescence measurements, we found the charge transfer between MoS2 and SWCNT is sensitive to the intensity of light field. We also demonstrate that SWCNT acts as p-type dopants at physical contact with monolayer MoS2. Our study gives new insight into the interaction between monolayer MoS2 and SWCNT, which may allow new phenomena and ideas for novel low dimensional hybrid materials.
