International Classification:

C23C 1600

US Classification:

118723E, 118723 R

Abstract:

An appparatus for confining plasma within a process zone of a substrate processing chamber. In one aspect, an apparatus comprises an annular member having an upper mounting surface, an inner confinement wall, and an outer confinement wall. The apparatus is disposed on or otherwise connected to a gas distribution assembly of the processing chamber to prevent plasma edge effects on the surface of a substrate. The apparatus provides a plasma choke aperture that reduces the volume of the process zone around the periphery of the substrate thereby eliminating uneven deposition of material around the edge of the substrate.

Abstract:

The present invention provides methods for synthesis of IV–VI nanostructures, and thermoelectric compositions formed of such structures. In one aspect, the method includes forming a solution of a Group IV reagent, a Group VI reagent and a surfactant. A reducing agent can be added to the solution, and the resultant solution can be maintained at an elevated temperature, e. g. , in a range of about 20 C. to about 360 C. , for a duration sufficient for generating nanoparticles as binary alloys of the IV–VI elements.

US Classification:

1362361, 136238, 136239, 136240

Abstract:

The present invention is generally directed to nanocomposite thermoelectric materials that exhibit enhanced thermoelectric properties. The nanocomposite materials include two or more components, with at least one of the components forming nano-sized structures within the composite material. The components are chosen such that thermal conductivity of the composite is decreased without substantially diminishing the composite's electrical conductivity. Suitable component materials exhibit similar electronic band structures. For example, a band-edge gap between at least one of a conduction band or a valence band of one component material and a corresponding band of the other component material at interfaces between the components can be less than about 5kT, wherein kis the Boltzman constant and T is an average temperature of said nanocomposite composition.

US Classification:

359334, 372 3, 372 4301, 977951

Abstract:

An optical device includes an input optical source that provides and optical signal to the optical device. A surface phonon polariton (SPP) nanostructure receives the optical signal that interacts with the SPP nanostructure to excite a Raman process and produce a Raman light signal. The Raman light signal comprises a broad spectral range from near infrared to far infrared.

US Classification:

310306, 310303, 136206

Abstract:

A surface-plasmon-coupled thermoelectric apparatus includes a first surface-plasmon substrate and a thermoelectric substrate electrically coupled to a plurality of electrodes. The substrates are electrically isolated from each other, and a first face of the thermoelectric substrate opposes a first face of the first surface-plasmon substrate to define a phonon insulating gap. A method of transferring thermal energy across the phonon insulating gap includes creating a first surface-plasmon polariton at the first surface-plasmon substrate when the first surface-plasmon substrate is coupled to a first thermal reservoir. Also included is creating a nonequilibrium state between the electron temperature and the phonon temperature at a first face of the thermoelectric substrate, when a second face of the thermoelectric substrate is coupled to a second thermal reservoir. Also included is coupling the first surface plasmon polariton with electrons in the thermoelectric substrate across the phonon insulating gap, thereby transferring thermal energy between the thermal reservoirs through the phonon insulating gap.

Abstract:

A method and apparatus for reducing instruction dependencies in extended SSA form instructions includes examining a first instruction of a worklist. The worklist contains instructions in the extended SSA form that have a source, a previous link and a write mask and further produce an output. The method and apparatus further includes examining at least one second instruction of the worklist, where the at least one second instruction is a source of the first instruction. Lastly, the method and apparatus includes translating the plurality of instructions in the worklist into a second plurality of instructions in the extended SSA form where the second plurality of instructions contains less instruction dependencies such as previous links.
