In this study, we experimentally investigate the carrier transport nonlinear behavior in back-gated graphene transistors. The graphene ribbons are monolayer graphene formed by chemical vapor deposition process and transferred on SiO2/Si substrate. The electrical characterization with a micro prober setup of hundreds of devices has been performed under vaccuum and for a temperature ranging from 300K down to 77K. We can distinguish two categories of electrical behavior, respectively, linear and nonlinear electrical output characteristics. The linear behavior excludes the impact of the Schottky barrier between both metallic source and drain contacts and graphene. The study is focused on the impact of the technological parameters on the electri...
