The corresponding resistivity of graphene sheets would be 10 −6 Ω⋅cm. This is less than the resistivity of silver, the lowest otherwise known at room temperature. [15] However, on SiO 2 substrates, scattering of electrons by optical phonons of the substrate is a larger effect than scattering by graphene's own phonons.

The corresponding resistivity of graphene sheets is 10 −8 Ω⋅m, lower than the resistivity of silver, which is the lowest known at room temperature. [82] However, on SiO 2 substrates, electron scattering by optical phonons of the substrate has a more significant effect than scattering by graphene's phonons, limiting mobility to 40 000 cm 2 ...
Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current.
Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used.
