Current crowding mediated large contact noise in graphene field-effect transistors

The performance of graphene field effect transistors is adversely affected by fluctuations in the electrical resistance at the graphene/metal interface. Here, the authors unveil the microscopic origin of such contact noise, highlighting the role of current crowding.
