Abstract:
A semiconductor light emitting element comprising:a substrate; and a multi-layered structure of nitride compound semiconductors having hexagonal crystal structure stacked on said substrate, said multi-layered structure including at least a first layer containing indium, and a second layer having a lattice constant smaller than that of said first layer, a distortion caused by lattice mismatch between said first layer and said second layer being applied to the crystal of said first layer, said indium contained in said first layer being mixed in said first layer, and a mole fraction of the indium in the first layer being within the miscibility gap range, said miscibility gap being a non-mixing composition range where uniformly mixed crystal relative to the composition of indium is not obtained, said first layer providing said miscibility gap.
