  • Patent number: 11220630
    Abstract: This disclosure relates to quantum dots with a core of III-V material, a first layer of II-VI material and an external shell of II-VI material to be used, for example, in downconverters. The external shell is preferably made of an alloy of Zn and Cd with Se or S. The inventors have demonstrated that introducing a small amount of Cd in the external shell provides excellent absorbance performance in blue, violet and UV wavelengths. The amount of Cd needed for this increase in absorbance can be very low. The inventors have shown that the emitted light can be nearly monochromatic, which is especially interesting in electronic applications.

After an oxidation between ?223° C. and 900° C., a MgO monolayer is produced where the Mg:O ratio is exactly 1:1 thereby avoiding underoxidized or overoxidized states associated with film defects. The process flow may be repeated one or more times to yield a desired thickness and resistance x area value when the MgO is a tunnel barrier or Hk enhancing layer. Moreover, a doping element (M) may be added during Mg deposition to modify the conductivity and band structure in the resulting MgMO layer.

  • Patent number: 10648069
    Abstract: A MgO layer is formed using a process flow wherein a Mg layer is deposited at a temperature <200° C. on a substrate, and then an anneal between 200° C. and 900° C., and preferably from 200° C. and 400° C., is performed so that a Mg vapor pressure >100.6 Torr is reached and a substantial portion of the Mg layer sublimes and leaves a Mg monolayer. After an oxidation between ?223° C. and 900° C., a MgO monolayer is produced where the Mg:O ratio is exactly 1:1 thereby avoiding underoxidized or overoxidized states associated with film defects. The process flow may be repeated one or more times to yield a desired thickness and resistance x area value when the MgO is a tunnel barrier or Hk enhancing layer. Moreover, a doping element (M) may be added during Mg deposition to modify the conductivity and band structure in the resulting MgMO layer.

  • Patent number: 10464307
    Abstract: A system and method for 3D microfabrication projects light capable of initiating photopolymerization toward a spatial light modulator that modulates light responsive to digital masks corresponding to layers of the structure. Projection optics focus the modulated light onto an optical plane within a photopolymerizable material supported on a stage. A computer controller causes the spatial light modulator to project a sequence of images corresponding to the digital masks while coordinating movement of the stage to move a position of the optical plane within the photopolymerizable material to sequentially project each image of the sequence to generate the structure by progressively photopolymerizing the photopolymerizable material.

  • Patent number: 10423035
    Abstract: It is possible to separate each liquid crystal display panel from a mother board in which multiple liquid crystal display panels are formed even with a thin glass substrate, by forming a columnar spacer in the boundary between liquid crystal display panels, forming a scribe line corresponding to the columnar spacer on both sides of the counter substrate and the TFT substrate in the mother board, and forming a separation line between the scribe lines by applying a bending stress to the mother board. Since the columnar spacer is formed in a portion corresponding to the scribe line, the strength in this portion increases, so that the proper scribe lines and break lines can be formed when the thickness of the glass substrate is reduced to about 0.15 mm.
