摘要：
Graphene oxide membranes up to 2000 mu m(2) in size can be synthesized with 90% yield in bulk quantities through a microwave-assisted chemical, method. Membranes are readily visualized on an oxidized silicon substrate, which enables efficient fabrication of electronic devices and sensors. Field effect transistors made of the membrane show ambipolar behavior, and their conductivity is significantly higher than previously reported values.
