Abstract
Official abstract text for this publication.
Light emitting devices and methods of manufacturing the light emitting devices. The light emitting devices include a silicon substrate; a metal buffer layer on the silicon substrate, a patterned dispersion Bragg reflection (DBR) layer on the metal buffer layer; and a nitride-based thin film layer on the patterned DBR layer and regions between patterns of the DBR layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a light emitting device, the method comprising: forming a reflection buffer layer structure including forming a metal buffer layer and forming a dispersion Bragg reflection (DBR) layer on a silicon substrate, wherein the forming the metal buffer layer includes using one of B and B 2 ; forming an XY material layer on the DBR layer, wherein X is at least one of Ti, Cr, Zr, Hf, Nb, and Ta, and Y is at least one of B, and B 2 ; and…
