21_12b/2009Thin Films: One Nanometer Thin Carbon Nanosheets with Tunable Conductivity and Stiffness (Adv. Mater. 12/2009)

Andrey Turchanin and co-workers report on page 1233 on the fabrication and characterization of atomically thin (∼1 nm) carbon films and membranes with tunable conductivity and stiffness, arbitrary size and shape. These carbon nanosheets are produced using self-assembled monolayers of aromatic molecules, which are cross-linked by electrons, detached from the surfaces, and subsequently pyrolized. The technical applicability of these novel materials is demonstrated by incorporating them into a microscopic pressure sensor. The optical microscopy image shows a folded nanosheet transferred onto an oxidized silicon wafer.
