    摘要: The present invention provides a method for suppressing transient enhanced diffusion of ion implanted dopants in a semiconductor substrate comprising bombarding the substrate in a vacuum with a beam of bubble-forming ions at a first temperature, a first energy, and a first ion dose sufficient to form a dispersion of bubbles at a depth equivalent to a peak of damage distribution in the substrate from implantation of dopant ions into the substrate in a vacuum at a second temperature, a second energy, and a second ion dose, said dispersion being sufficient to reduce said damage distribution.

    摘要: The present invention provides a new class of precursors for forming an improved diamond-like carbon coating on a workpiece. The precursors of the present invention are paraxylylenes, preferably dimers of paraxylylene, which are solid at room temperature and which will vaporize, pyrolize to substantially monomeric form, condense onto a workpiece, and spontaneously polymerize to form a "parylene" film which is free of precursor droplets and absorbed water. Upon bombardment with an ion beam, the parylene film is converted into a uniform, pinhole-free DLC coating.

    摘要: The present invention relates to an ion beam assisted method of producing a diamond like carbon (DLC) coating on the surface of a material. More particular, the invention relates to an ion beam assisted method using a fullerene precursor to produce a DLC coating, wherein the chemical composition of the ion beam and precursor are selectively chosen to determine the physical properties of the DLC coating.

    摘要: A process for hardening the surface of a metal body in which the surface is first bombarded with ions capable of occupying interstitial sites in its crystal lattice, then a coating of a reactive metal is deposited on the surface, and finally the coating is bombarded with ions which will react with it to form a hard material such as a carbide or nitride. The bombardment is continued until the hard material has become embodied in the surface by means of radiation enhanced diffusion.

    摘要: Fuel cell electrodes comprising a minimal load of catalyst having maximum catalytic activity and a method of forming such fuel cell electrodes. The preferred method comprises vaporizing a catalyst, preferably platinum, in a vacuum to form a catalyst vapor. A catalytically effective amount of the catalyst vapor is deposited onto a carbon catalyst support on the fuel cell electrode. The electrode preferably is carbon cloth. The method reduces the amount of catalyst needed of a high performance fuel cell electrode to about 0.3 mg/cm2 or less, preferably to about 0.1 mg/cm2. The electrocatalytic layer formed comprises unique, rod-like structures.
