Graphene Noise Patterns (image) DOE/Lawrence Berkeley National Laboratory Caption In the noise models developed at Berkeley Lab's Molecular Foundry, all single layer graphene samples show an M-shaped pattern of noise (top) while all bi-layer graphene samples show a V-shaped noise pattern (bottom). This information will help the development of future graphene devices.
