Graphene is a fascinating material for exploring fundamental science questions as well as a potential
building block for novel electronic applications. In order to realize the full potential of this material
the fabrication techniques of graphene devices, still in their infancy, need to be refined to better
isolate the graphene layer from the environment. We present results from a study on the influence of
extrinsic factors on the quality of graphene devices including material defects, lithography, doping
by metallic leads and the substrate. The main finding is that trapped Coulomb scatterers associated
with the substrate are the primary factor reducing the quality of graphene devices. A fabrication
scheme is proposed to produce high quality graphene devices dependably and reproducibly. In these
devices, the transport properties approach theoretical predictions of ballistic transport.
