Patent number: 7258895Abstract: The invention includes methods of forming material on a substrate and methods of forming a field effect transistor gate oxide. In one implementation, a first species monolayer is chemisorbed onto a substrate within a chamber from a gaseous first precursor. The first species monolayer is discontinuously formed over the substrate. The substrate having the discontinuous first species monolayer is exposed to a gaseous second precursor different from the first precursor effective to react with the first species to form a second species monolayer, and effective to form a reaction product of the second precursor with substrate material not covered by the first species monolayer. The substrate having the second species monolayer and the reaction product is exposed to a third gaseous substance different from the first and second precursors effective to selectively remove the reaction product from the substrate relative to the second species monolayer. Other implementations are contemplated.Type: GrantFiled: August 6, 2003Date of Patent: August 21, 2007Assignee: Micron Technology, Inc.Inventor: Gurtej S. Sandhu

Patent number: 7241479Abstract: The present invention is generally directed to a novel process for the production of nanowires and nanobelts and the novel nanostructures which can be produced according to the disclosed processes. The process can be carried out at ambient pressure and includes locating a metal in a reaction chamber, heating the chamber to a temperature at which the metal becomes molten, and flowing a vapor-phase reactant through the chamber. The vapor-phase reactant and the molten metal can react through a thermal CVD process, and nanostructures can form on the surface of the molten metal. Dimensions of the nanostructures can be controlled by reaction temperature.Type: GrantFiled: August 22, 2003Date of Patent: July 10, 2007Assignee: Clemson UniversityInventors: Apparao M.

Patent number: 7087266Abstract: A thermal barrier coating, or TBC, and method for forming the TBC. The TBC is formed of a thermal-insulating material that contains yttria-stabilized zirconia (YSZ) alloyed with at least a third oxide. The TBC is formed to also contain elemental carbon, and may potentially contain carbides and/or a carbon-containing gas that forms from the thermal decomposition of carbon. The TBC is characterized by lower density and thermal conductivity, high temperature stability and improved mechanical properties. To exhibit the desired effect, the third oxide is more particularly one that increases the lattice strain energy of the TBC microstructure as a result of having an ion size that is sufficiently different than a zirconium ion.Type: GrantFiled: June 18, 2004Date of Patent: August 8, 2006Assignee: General Electric CompanyInventors: Ramgopal Darolia, Boris A.
