a Schematic of the experimental setup for the thermopower measurements. b The thermoelectromotive force and the temperature difference profiles of both pristine and doped graphene samples on a glass substrate (Sample #1). c Schematic of the experimental setup for the Hall effect measurements. Parameters Ix and VHall correspond to the constant current and the Hall voltage, respectively. d The magnetic-field dependencies of the Hall resistance (RHall = VHall/Ix) in both pristine and doped graphene samples on a glass substrate (Sample #1)
