Patent ID: 8415654

Claim:
A light-emitting device comprising: a. an ultraviolet light-emitting structure having i. a first layer with a first conductivity, wherein said first layer comprises a first portion having a surface with an amount of elemental indium, said first portion surface being treated by a silicon containing precursor source and a second portion having a surface with an amount of elemental indium; said first layer comprises of plurality of said first portion and said second portion; ii. a second layer with a second conductivity; and iii. a light emitting quantum well region between above said first layer and second layer; b. a first electrical contact in electrical connection with said first layer; c. a second electrical contact in electrical connection with said second layer; and d. a template serving as a platform for said light-emitting structure; and whereby, when an electrical potential is applied to said first electrical contact and said second electrical contact said device emits ultraviolet light; and further comprising a layer between said first portion and said second portion of said first layer, said layer comprising an amount of elemental silicon and an amount of elemental indium.
