Abstract We present the phonon-limited electron mobility in planar T graphene and find that the mobility ∝ T − 5 . 53 at low temperature T. With the increase of temperature, the power exponent 5.53 decreases towards 1. Excitingly, the room-temperature mobility of planar T graphene is 2 . 78 × 1 0 6 cm 2 /Vs which is about 20.59 times as large as that of n -type graphene at the same carrier density. Different from graphene with longitudinal acoustic phonon dominating the mobility, an in-plane optical phonon mode contributes the most to the mobility of planar T graphene.
