  • Patent number: 7382017
    Abstract: Methods and apparatuses for nanoenabled memory devices and anisotropic charge carrying arrays are described. In an aspect, a memory device includes a substrate, a source region of the substrate, and a drain region of the substrate. A population of nanoelements is deposited on the substrate above a channel region, the population of nanolements in one embodiment including metal quantum dots. A tunnel dielectric layer is formed on the substrate overlying the channel region, and a metal migration barrier layer is deposited over the dielectric layer. A gate contact is formed over the thin film of nanoelements. The nanoelements allow for reduced lateral charge transfer. The memory device may be a single or multistate memory device.

  • Patent number: 7326365
    Abstract: Temperature-sensing compositions can include an inorganic material, such as a semiconductor nanocrystal. The nanocrystal can be a dependable and accurate indicator of temperature. The intensity of emission of the nanocrystal varies with temperature and can be highly sensitive to surface temperature. The nanocrystals can be processed with a binder to form a matrix, which can be varied by altering the chemical nature of the surface of the nanocrystal. A nanocrystal with a compatibilizing outer layer can be incorporated into a coating formulation and retain its temperature sensitive emissive properties.

  • Patent number: 7250082
    Abstract: Provided is a chemical wet preparation method for Group 12-16 compound semiconductor nanocrystals. The method includes mixing one or more Group 12 metals or Group 12 precursors with a dispersing agent and a solvent followed by heating to obtain a Group 12 metal precursor solution; dissolving one or more Group 16 elements or Group 16 precursors in a coordinating solvent to obtain a Group 16 element precursor solution; and mixing the Group 12 metal precursors solution and the Group 16 element precursors solution to form a mixture, and then reacting the mixture to grow the semiconductor nanocrystals. The Group 12-16 compound semiconductor nanocrystals are stable and have high quantum efficiency and uniform sizes and shapes.
