Abstract (en)

[origin: WO2023280951A1] Methods for producing layered nanocarbon structures placing a workpiece in a working chamber, applying a vacuum to the chamber, processing the workpiece surface with gas ions, applying a material sublayer to the workpiece surface, depositing carbon ions from a carbon plasma on the workpiece surface to apply an amorphous diamond-like sp3 carbon coating layer on the workpiece surface. The methods include irradiating the growing carbon coating with accelerated ions of an inert gas at a first energy range to apply a graphite sp2 carbon coating layer on the sp3 carbon coating layer and irradiating the growing carbon coating with accelerated ions of the inert gas at a second energy range, different from the first energy range, to apply a linear chain and polymer sp1 carbon coating layer on the sp2 carbon coating layer.
