text: Although GFETs based on wide-channel monolayer graphene have already been demonstrated, with some of them surpassing the performance of their Si counterparts in certain respects and some of them exploiting the ambipolar characteristics which are absent in conventional FETs, these do not appear to be viable options for logic applications due to the lack of a band gap and associated poor ON/OFF current ratios.
