  • Publication number: 20230253193
    Abstract: A substrate support for a substrate processing system includes a baseplate and a spray coat layer arranged on the baseplate. The spray coat layer has a first thickness and a first thermal conductivity. A bond layer is arranged on the spray coat layer. The bond layer has a second thickness and a second thermal conductivity. A ceramic layer is arranged on the bond layer. At least one of the first thickness and the second thickness varies in at least one of a radial direction and an azimuthal direction such that a third thermal conductivity between the ceramic layer and the baseplate varies in the at least one of the radial direction and the azimuthal direction.

  • Patent number: 11499248
    Abstract: An electric field drives nanocrystals dispersed in solvents to assemble into ordered three-dimensional superlattices. A first electrode and a second electrode 214 are in the vessel. The electrodes face each other. A fluid containing charged nanocrystals fills the vessel between the electrodes. The electrodes are connected to a voltage supply which produces an electrical field between the electrodes. The nanocrystals will migrate toward one of the electrodes and accumulate on the electrode producing ordered nanocrystal accumulation that will provide a superlattice thin film, isolated superlattice islands, or coalesced superlattice islands.

  • Patent number: 11305252
    Abstract: An ultra low density film and an ultra low density solid material are produced by the steps of providing a vessel, introducing two immiscible fluids into the vessel, adding nanocrystals to at least one of the two immiscible fluids, applying a shear force to the two immiscible fluids and the nanocrystals in a manner that causes the nanocrystals to self-assemble and form colloidosomes. The colloidosomes amass and evaporation of the two fluids produces dried colloidosomes. The ultra low density self-assembled colloidosomes are hollow self-assembled colloidosomes, which are formed into the ultra-low density film and the ultra-low density solid.

  • Patent number: 10557855
    Abstract: Systems comprising a nanocrystal and a luminescent chromophore are disclosed herein. The luminescent chromophore can emit energy having a first wavelength. The luminescent chromophore is configured to transfer the emitted energy having a first wavelength to the nanocrystal. The luminescent chromophore can be linked to the nanocrystal via a covalent bond. Absorption of the energy having first wavelength by the nanocrystal can activate the nanocrystal and result in an increase in quantum yield. In some embodiments, the nanocrystal can include silicon, germanium, carbon, or combinations thereof. In some examples, the luminescent chromophore can be pyrene. The luminescent chromophore and the silicon containing nanocrystal can be in a ratio of about 1:1 to 100:1 in the nanocrystal system. Methods of making and using the system are also disclosed.
