Abstract

We have developed a lithography-free, all-dry process for fabricating graphene devices using an ultrathin quartz filament as a shadow mask to avoid possible contamination of graphene during lithographic process. This technique was used to prepare devices for electrical transport as well as planar tunnel junction studies of n-layer graphene (nLG), with n = 1, 2, 3 and higher. We observed localization behavior and an apparent reduction of density of states (DOS) near the Fermi energy in nLG.
