Large-scale Growth and Simultaneous Doping of Molybdenum Disulfide Nanosheets
A facile method that uses chemical vapor deposition (CVD) for the simultaneous growth and doping of large-scale molybdenum disulfide (MoS(2)) nanosheets was developed. We employed metalloporphyrin as a seeding promoter layer for the uniform growth of MoS(2) nanosheets. Here, a hybrid deposition syst...

Sumario: | A facile method that uses chemical vapor deposition (CVD) for the simultaneous growth and doping of large-scale molybdenum disulfide (MoS(2)) nanosheets was developed. We employed metalloporphyrin as a seeding promoter layer for the uniform growth of MoS(2) nanosheets. Here, a hybrid deposition system that combines thermal evaporation and atomic layer deposition (ALD) was utilized to prepare the promoter. The doping effect of the promoter was verified by X-ray photoelectron spectroscopy and Raman spectroscopy. In addition, the carrier density of the MoS(2) nanosheets was manipulated by adjusting the thickness of the metalloporphyrin promoter layers, which allowed the electrical conductivity in MoS(2) to be manipulated. |
