I measured the transport properties of graphene nanoribbons as a function of the charged impurity density in ultra-high vacuum to directly probe the effect of dimensional confinement. Coulomb impurities create charge puddles in graphene sheets, which dominate transport properties. My results shed light on recent predictions about the fundamental mechanisms behind gaps in conductance that appear in transport measurements.
