    摘要: The present invention relates to a fabrication method of nitride-based semiconductors and a nitride-based semiconductor fabricated thereby. In the fabrication method of the invention, a self-organizing metal layer is formed on a sapphire substrate. The sapphire substrate having the self-organizing metal layer is heated so that self-organizing metal coalesces into nanoscale clusters to irregularly expose an upper surface of the sapphire substrate. Exposed portions of the sapphire substrate is plasma etched using the self-organized metal clusters as a mask to form a nanoscale uneven structure on the sapphire substrate. A resultant structure is wet etched to remove the self-organized metal clusters. The nanoscale uneven structure formed on the sapphire substrate decreases the stress and resultant dislocation between the sapphire substrate and a nitride-based semiconductor layer as well as increases the quantum efficiency between the same.

    摘要: A method of forming a nitride semiconductor device is disclosed. An n-type GaN layer is formed on a substrate. A self assembled nitride semiconductor quantum dot layer is formed on the n-type GaN layer by growing InyGa(1-y)N (0.3≦y≦1) directly on the n-type GaN layer. A resonance tunnel layer is formed on the n-type GaN layer to cover the nitride semiconductor quantum dot layer. An active layer is formed on the resonance tunnel layer. A p-type nitride semiconductor layer is formed on the active layer. The active layer contains a quantum well layer and a quantum barrier layer, and the resonance tunnel layer has a band gap energy greater than that of the quantum well layer.
