They found that a single layer of carbon reduced the friction of the silicon carbide surface by a factor of two, and that the graphene bilayer reduced the friction by another fraction of two. The strange thing is that both single and bilayer graphene had less friction than graphite. On the face of it, one would expect the friction to stay somewhere between the values of uncoated silicon carbide and the graphite value as graphene layers were added, without passing through a minimum or maximum along the way.
