CVD Monolayer Graphene Description
CVD-Monolayer-Graphene on SiO2 Substrate refers to a method for synthesising graphene, a single layer of carbon atoms arranged in a hexagonal lattice, on a silicon dioxide surface utilising chemical gas phase deposition processes.
Monolayer graphene refers to a sole layer of carbon atoms arranged in a hexagonal pattern. This single layer exhibits distinct electrical, thermal and mechanical properties that differ from those of bulk graphite or other carbon forms.
Silicon dioxide (SiO2) is commonly used as a substrate in semiconductor technology and microelectronics because of its high insulating capability, thermal stability and compatibility with standard lithographic techniques.
