Description

technical field [0001] The invention relates to a device for preparing new materials, in particular to a device for large-scale and continuous preparation of novel two-dimensional nanomaterials such as graphene, metal chalcogenides, silicene, germanene, and boron nitride. Background technique [0002] Graphene has excellent two-dimensional electrical, optical, thermal, mechanical properties and chemical stability. Graphene has broad application prospects in ultrafast optoelectronic devices, clean energy, sensors, etc. The transmission speed of electrons in graphene is 150 times that of silicon. Famous companies such as IBM have prepared ultra-fast optoelectronic devices with speeds up to terahertz. The University of California in the United States has developed an optical modem using graphene, which is expected to increase the network speed by 10,000 times; The global annual demand for semiconductor crystal silicon is about 2,500 tons. If graphene replaces one-tenth of cryst...
