  • Publication number: 20120006408
    Abstract: Designs of extremely high efficiency solar cells are described. A novel alternating bias scheme enhances the photovoltaic power extraction capability above the cell band-gap by enabling the extraction of hot carriers. When applied in conventional solar cells, this alternating bias scheme has the potential of more than doubling their yielded net efficiency. When applied in conjunction with solar cells incorporating quantum wells (QWs) or quantum dots (QDs) based solar cells, the described alternating bias scheme has the potential of extending such solar cell power extraction coverage, possibly across the entire solar spectrum, thus enabling unprecedented solar power extraction efficiency. Within such cells, a novel alternating bias scheme extends the cell energy conversion capability above the cell material band-gap while the quantum confinement structures are used to extend the cell energy conversion capability below the cell band-gap.

  • Publication number: 20110310915
    Abstract: Methods and apparatus for improved single-mode selection in a quantum cascade laser. In one example, a distributed feedback grating incorporates both index-coupling and loss-coupling components. The loss-coupling component facilitates selection of one mode from two possible emission modes by periodically incorporating a thin layer of “lossy” semiconductor material on top of the active region to introduce a sufficiently large loss difference between the two modes. The lossy layer is doped to a level sufficient to induce considerable free-carrier absorption losses for one of the two modes while allowing sufficient gain for the other of the two modes. In alternative implementations, the highly-doped layer may be replaced by other low-dimensional structures such as quantum wells, quantum wires, and quantum dots with significant engineered intraband absorption to selectively increase the free-carrier absorption losses for one of multiple possible modes so as to facilitate single-mode operation.

  • Publication number: 20110284068
    Abstract: The disclosed subject matter provides a method and structure for obtaining ultra-low surface recombination velocities from highly efficient surface passivation in crystalline silicon substrate-based solar cells by utilizing a bi-layer passivation scheme which also works as an efficient ARC. The bi-layer passivation consists of a first thin layer of wet chemical oxide or a thin hydrogenated amorphous silicon layer. A second layer of amorphous hydrogenated silicon nitride film is deposited on top of the wet chemical oxide or amorphous silicon film. This deposition is then followed by annealing to further enhance the surface passivation.

  • Publication number: 20110284978
    Abstract: A radiation converter includes a directly converting semiconductor layer, wherein the semiconductor layer includes grains whose interfaces at least predominantly run parallel to a drift direction—constrained by an electric field—of electrons liberated in the semiconductor layer. in at least one embodiment, the charge carriers liberated by incident radiation quanta are accelerated in the electric field in the direction of the radiation incidence direction and on account of the columnar or pillar-like texture of the semiconductor layer, in comparison with the known radiation detectors, cross significantly fewer interfaces of the grains that are occupied by defect sites. This increases the charge carrier lifetime/mobility product in the direction of charge carrier transport. Consequently, it is possible to realize significantly thicker semiconductor layers for the counting and/or energy-selective detection of radiation quanta.

    Abstract: An interconnect structure that includes a dielectric material having a dielectric constant of about 3.0 or less is provided. This low k dielectric material has at least one conductive material having an upper surface embedded therein. The dielectric material also has a surface layer that is made hydrophobic prior to the formation of the noble metal cap. The noble metal cap is located directly on the upper surface of the at least one conductive material. Because of the presence of the hydrophobic surface layer on the dielectric material, the noble metal cap does not substantially extend onto the hydrophobic surface layer of the dielectric material that is adjacent to the at least one conductive material and no metal residues from the noble metal cap deposition form on this hydrophobic dielectric surface.

According to the nanocrystal electroluminescence device, since the hole transport layer, the nanocrystal light-emitting layer and the electron transport layer are completely separated from one another, the electroluminescence device provides a pure nanocrystal luminescence spectrum having limited luminescence from other organic layers and substantially no influence by operational conditions, such as voltage. Further included is a method for fabricating the nanocrystal electroluminescence device.

  • Publication number: 20110278730
    Abstract: A structure having air gaps between interconnects is disclosed. A first insulating material is deposited over a workpiece, and a second insulating material having a sacrificial portion is deposited over the first insulating material. Conductive lines are formed in the first and second insulating layers. The second insulating material is treated to remove the sacrificial portion, and at least a portion of the first insulating material is removed, forming air gaps between the conductive lines. The second insulating material is impermeable as deposited and permeable after treating it to remove the sacrificial portion. A first region of the workpiece may be masked during the treatment, so that the second insulating material becomes permeable in a second region of the workpiece yet remains impermeable in the first region, thus allowing the formation of the air gaps in the second region, but not the first region.

A mirror that primarily reflects photons of longer visible wavelengths is disposed on the back side of the semiconductor layer.

  • Publication number: 20110278532
    Abstract: A memory using a tunnel barrier that has a variable effective width is disclosed. A memory element includes a tunneling barrier and a conductive material. The conductive material typically has mobile ions that either move towards or away from the tunneling barrier in response to a voltage across the memory element. A low conductivity region is either formed or destroyed. It can be formed by either the depletion or excess ions around the tunneling barrier, or by the mobile ions combining with complementary ions. It may be destroyed by either reversing the forming process or by reducing the tunneling barrier and injecting ions into the conductive material. The low conductivity region increases the effective width of the tunnel barrier, making electrons tunnel a greater distance, which reduces the memory element's conductivity. By varying conductivity multiple states can be created in the memory cell.

    Abstract: This invention relates to materials and processes for thin film deposition on solid substrates. Silica/alumina nanolaminates were deposited on heated substrates by the reaction of an aluminum-containing compound with a silanol. The nanolaminates have very uniform thickness and excellent step coverage in holes with aspect ratios over 40:1. The films are transparent and good electrical insulators. This invention also relates to materials and processes for producing improved porous dielectric materials used in the insulation of electrical conductors in microelectronic devices, particularly through materials and processes for producing semi-porous dielectric materials wherein surface porosity is significantly reduced or removed while internal porosity is preserved to maintain a desired low-k value for the overall dielectric material.
