- Abstract
- We produced graphene-based field-effect transistors by contacting mono- and bi-layer
graphene by sputtering Ni or Ti as metal electrodes. We performed electrical characterization
of the devices by measuring their transfer and output characteristics. We clearly observed the
presence of a double-dip feature in the conductance curve for Ni-contacted transistors, and we
explain it in terms of charge transfer and graphene doping under the metal contacts. We also
studied the contact resistance between the graphene and the metal electrodes with larger
values of ?30 k??m2 recorded for Ti contacts. Importantly, we prove that the contact
resistance is modulated by the back-gate voltage. (literal)
