- Abstract
- Few layer graphene (FLG) samples contacted were irradiated with protons at an energy of 5 MeV and doses up to 2 X 10(15)/cm(2). The electrical properties of ungated FLG sheets contacted by Pd/Au in a source (S)-drain (D) configuration, including V(DS)-I(DS), V(G)-I(DS), and the hole mobility, were compared before and after proton irradiation. After irradiation, it is observed that the ambipolar conduction of the FLG sheets was changed to a p-type conduction. The field-effect mobility of the hole carriers and the resistance in the graphene sheets greatly decreased because the proton irradiation increased the number of the surface states.
