One Nanometer Thin Carbon Nanosheets with Tunable Conductivity and Stiffness

Abstract

Atomically thin (∼1 nm) carbon films and membranes whose electrical behavior can be tuned from insulating to conducting are fabricated by a novel route. These films present arbitrary size and shape based on molecular self-assembly, electron irradiation, and pyrolysis, and their technical applicability is demonstrated by their incorporation into a microscopic pressure sensor.
