  Since the first graphene layer was fabricated in the early 2000's, graphene
properties have been studied extensively both experimentally and theoretically.
However, when comparing the many resistivity models reported in literature,
several discrepancies can be found, as well as a number of inconsistencies
between formulas. In this paper, we revise the main scattering mechanisms in
graphene, based on theory and goodness of fit to in-house experimental data. In
particular, a step-by-step evaluation of the interaction between electrons and
optical phonons is carried out, where we demonstrate that the process of
optical phonon emission scattering is completely suppressed for all low-field
applications and all temperatures in the range of interest, as opposed to what
is often reported in literature. Finally, we identify the best scattering
models based on the goodness of fit to experimental data.
