Abstract:
Systems and methods are disclosed herein for forming defects on graphitic materials. The methods for forming defects include applying a radiation reactive material on a graphitic material, irradiating the applied radiation reactive material to produce a reactive species, and permitting the reactive species to react with the graphitic material to form defects. Additionally, disclosed are methods for removing defects on graphitic materials.
Abstract:
The disclosed subject matter provides techniques for the controllable low temperature fabrication of graphitic carbon. The disclosed subject matter also provides a chemical process using commercially available hydrocarbon for the preparation of graphitic carbon, including carbon nanotubes and sheets.
Abstract:
Methods are disclosed that include exposing, in direct succession, portions of a surface of a sample to a charged particle beam, the portions of the surface of the sample forming a row in a first direction, the charged particle beam having an average spot size f at the surface of the sample, each portion being spaced from its neighboring portions by a distance of at least d in the first direction, and a ratio d/f being 2 or more.
