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×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: 11298957
    Abstract: A laser panel, a laser array device, and a laser display. The laser panel and the laser array device separately comprise multiple groups of independent laser light source modules; each group of laser light source modules comprises plural light sources; the plural light sources are all produced by inkjet printing; the laser display and a voltage-driven laser display separately comprise the laser panel. Producing a laser panel by inkjet printing provides a novel technical solution for cheap and industrial manufacturing of laser panels. It is difficult to generate laser coherent superposition between the light emitted by the laser light source module, and therefore, speckles caused by laser coherence in conventional laser display technologies are greatly eliminated. The present invention achieves a voltage-driven laser display, and facilitates achieving a better display effect while reducing the volume of the display.
