The intrinsic doping level of graphene prepared by mechanical exfoliation andstandard lithography procedures on thermally oxidized silicon variessignificantly and seems to depend strongly on processing details and thesubstrate morphology. Moreover, transport properties of such graphene devicessuffer from hysteretic behavior under ambient conditions. The hysteresispresumably originates from dipolar adsorbates on the substrate or graphenesurface. Here, we demonstrate that it is possible to reliably obtain lowintrinsic doping levels and to strongly suppress hysteretic behavior even inambient air by depositing graphene on top of a thin, hydrophobic self assembledlayer of hexamethyldisilazane (HMDS). The HMDS serves as a reproducibletemplate that prevents the adsorption of dipolar substances. It may also screenthe influence of substrate deficiencies.
