    摘要: A method and semiconductor device for synthesizing graphene using ion implantation of carbon. Carbon is implanted in a metal using ion implantation. After the carbon is distributed in the metal, the metal is annealed and cooled in order to precipitate the carbon from the metal to form a layer of graphene on the surface of the metal. The metal/graphene surface is then transferred to a dielectric layer in such a manner that the graphene layer is placed on top of the dielectric layer. The metal layer is then removed. Alternatively, recessed regions are patterned and etched in a dielectric layer located on a substrate. Metal is later formed in these recessed regions. Carbon is then implanted into the metal using ion implantation. The metal may then be annealed and cooled in order to precipitate the carbon from the metal to form a layer of graphene on the metal's surface.

    摘要: A free-standing cremation memorial for holding cremated remains has a plurality of chambers in a vertical portion of the structure as well as a number of chambers in the base unit. A base member prefabricated of aluminum framework with at least about 10 underground chambers is provided. An upright framework supported on said base in which a large number of niches is provided. A base member, which is supported on concrete footings, is a three-dimensional framework which provides support for the upright portion of the cremation memorial, which is also prefabricated framework.

    摘要: A resonant tunneling diode (400) made of a silicon quantum well (406) with silicon oxide tunneling barriers (404, 408). The tunneling barriers have openings (430) of size smaller than the electron wave packet spread to insure crystal alignment through the diode without affecting the tunneling barrier height, and the openings (430) have an irregular (nonperiodic) shape.
