Patent ID: 8835961

Claim:
An optoelectronic device comprising a first component comprising a Group III-N semiconductor, and a second component comprising a bimetallic oxide containing tin; wherein the first component is in optical contact with the second component; wherein the second component has an index of refraction within 15% of the index of refraction of the first component at wavelengths of light emitted or absorbed by the Group III-N semiconductor; wherein the second component has a negligible extinction coefficient at wavelengths of light emitted or absorbed by the Group III-N semiconductor; and wherein the bimetallic oxide comprises one of Zn 2 SnO 2 , Sn 1-x Bi x O 2 having 0.08<x<0.12, Sn 1-x Al x O 2 having 0.15<x<0.21, or Sn 1-x Mg x O 2 having 0.14<x<0.18.
