Properties of Graphene Film:

 

The thickness and quality of our graphene films is controlled by Raman Spectroscopy. 

The graphene coverage of this product is about 95%

The graphene film is continuous, with occasional holes and cracks

The graphene film is polycrystalline, i.e. it consists of grains with different crystallographic orientation

Sheet Resistance: 660-1,500 Ω/square
