NON-POLAR LED EPITAXIAL PLATE OF BLUE GLOW ON SUBSTRATE OF LAO AND METHOD OF ITS PRODUCTION Russian patent published in 2018 - IPC H01L33/12 H01L33/32 

FIELD: physics.

SUBSTANCE: non-polar LED epitaxial plate of blue glow on a substrate of lanthanum aluminate (LAO) containing layers successively deposited on a LAO substrate: a buffer layer made of GaN with a non-polar face m; the first unalloyed layer, which is a non-polar undoped layer of u-GaN; the first doped layer, which is a non-polar doped GaN film of type n; a layer of the quantum well, which is a non-polar layer of a quantum well of InGaN/GaN; an electronic inversion layer, which is an electronic inversion layer of AlGaN with a non-polar face m; and the second doped layer, which is a non-polar doped film of GaN of type p. A method for producing a non-polar LED epitaxial plate of blue glow on an LAO substrate is also provided.

EFFECT: inventions provide a low defect density, a high quality, and good optical characteristics at a low cost of production.
