Fig. 1From: Uniformly Nanopatterned Graphene Field-Effect Transistors with Enhanced PropertiesSchematic of nanopatterned graphene fabrication. a CVD-grown graphene was transferred onto a Si/SiO2 substrate. b An AAO template was placed on top of graphene. c Graphene in the exposed area was etched away by O2 plasma through the AAO pores, and then the AAO was removed. Finally, porous graphene on SiO2 was obtainedBack to article page
