Scale-invariant large nonlocality in polycrystalline graphene

Nonlocal resistances in graphene Hall bars attributed to neutral current Hall effects have been mainly measured at the microscale. Here, the authors observe consistently strong nonlocal signals in Hall bars with channel length ranging from the micrometer up to the millimeter scale, and explain them...
