Claim Text:
1. A light emitting diode device having a super lattice structure layer, comprising: a silicon-based substrate; a buffer layer formed on the silicon-based substrate, wherein the buffer layer comprises aluminum gallium nitride (AlGaN); a super lattice structure layer formed on the buffer layer such that the buffer layer is between the silicon-based substrate and the super lattice structure layer, wherein the super lattice structure layer is composed of multi-layer of aluminum gallium nitride/gallium nitride (AlGaN/GaN) pairs and piled up by 2 nm scale dielectric materials such as 1 nm/1 nm, 2 nm/2 nm or 2 nm/6 nm of aluminum gallium nitride/gallium nitride (AlGaN/GaN); a nano-structure layer formed in contact with the super lattice structure layer, wherein the nano-structure layer is selected from the group consisting of silicon dioxide (SiO a first semiconductor layer formed on the nano-structure layer and portions of the first semiconductor layer are in contact with the super lattice structure layer, wherein the first semiconductor layer is n-type GaN; a light emitting layer formed on the first semiconductor layer, wherein the light emitting layer is selected from the group consisting of single Quantum well and multi-Quantum well; and a second semiconductor layer formed on the light emitting layer, and the second semiconductor layer is p-type GaN.
