a A schematic of the experimental setup for the thermopower measurements. The right-side temperature (TA) and the left-side temperature (TB) are measured by K-type (alumel–chromel) thermocouples. b The ΔV – ΔT profiles measured at various gate voltages. The red and blue colors indicate the hole and electron carriers, respectively. c The Seebeck coefficient in the EDLT of large-area graphene on the flexible substrate as a function of VG – VCNP. d The power factor (S2σ) in the EDLT of large-area graphene on the flexible substrate as a function of VG – VCNP
