Patent ID: 7023024

Claim:
A light emitting diode comprising: (a) a diamond substrate; (b) a first aluminum gallium nitride layer above said diamond substrate having same conductivity type as said substrate; (c) a quantum well structure on said first aluminum gallium nitride layer formed of a plurality of repeating sets of alternating layers selected from the group consisting of GaN, In x Ga 1-x N, where 0<x<1, and Al x In y Ga 1-x-y N where 0<x<1 and 0<y<1 and 0<x+y<1; (d) a second aluminum gallium nitride layer on said quantum well structure having conductivity type opposite of said first aluminum gallium nitride layer; (e) a contact structure on said second aluminum gallium nitride layer having conductivity type opposite of said substrate and said first aluminum gallium nitride layer; (f) an ohmic contact to said diamond substrate; and (g) an ohmic contact to said contact structure.
