  • METHODS OF FORMING FILMS
    Publication number: 20180245213
    Abstract: A method of forming a layer, the method including providing a feedstock, the feedstock including a first component and a second component; ionizing at least part of the feedstock thereby forming a plasma, wherein the plasma includes constituents selected from: the first component, derivatives of the first component, ions of the first component, ions of derivatives of the first component, the second component, derivatives of the second component, ions of the second component, ions of derivatives of the second component, or combinations thereof, and wherein the individual identities, individual ratios, total quantities, or any combination thereof of the first and second component in the feedstock can modulate the makeup of the plasma; forming a beam from the plasma; and forming a layer from the beam, wherein the layer includes at least some portion of at least the first or the second component.

  • Process for production of ultrathin protective overcoats
    Patent number: 6743481
    Abstract: A multilayer coating of fullerene molecules is deposited on a substrate, and layers of the multilayer coating are removed leaving an approximate monolayer coating of fullerene molecules on the substrate. In some embodiments, a beam generator, such as an ion beam, electron beam or laser generator, produces a beam arranged to break the weaker fullerene-to-fullerene intermolecular bond of the multilayer coating and inadequate to break the stronger fullerene-to-substrate association/bond of the coating. The beam is directed at the multilayer coating to break the fullerene-to-fullerene intermolecular bond. In other embodiments, the monolayer of fullerene molecules is formed by applying a solvent to the multilayer coating to break the fullerene-to-fullerene intermolecular bond of the multilayer coating.
