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.
