抄録

Thin films of crystalline molybdenum disulfide (MoS2) are grown by friction-induced synthesis at the interface between a n+-Si(1 0 0) substrate and a synthetic quartz ball. The thin films are formed as a result of the tribochemical reaction of molybdenum dithiocarbamates (MoDTC) in synthetic oil under sliding friction conditions. Raman mapping shows the width of the grown MoS2 film to be about 7 µm, and the difference between the Raman frequencies of the E12g and A1g modes indicate that there are more than 6 monolayers in the MoS2 film. A TEM image indicates that a layer-by-layer structure is formed at the top surface of the stacked films. These results show that it is possible to fabricate a 2D layered MoS2 film on a non-metal surface using this friction induced crystal growth method.
