摘要：

We report on SEM, AFM, and Raman identification of non-planar several monolayer-thick graphene nanostructures with curved shapes. During mechanical exfoliation we obtained graphene flakes with nanowire/nanotube-like objects (diameters between 8 and 35 nm) with cross-sectional profile reminiscent of the Greek capital letter omega (Omega). The curved shapes of these objects were confirmed by AFM and SEM imaging. Non-planar Omega - nanostructures open up new possibilities for graphene electron energy band engineering.
