摘要：
We present the phonon-limited electron mobility in planar.. graphene and find that the mobility proportional to 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 x 10(6) cm(2)/Vs which is about 20.59 times as large as that of T-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.
