摘要:
A method for producing an epitaxial wafer includes a step of growing an epitaxial layer structure on a III-V semiconductor substrate, the epitaxial layer structure including a III-V semiconductor multiple-quantum well and a III-V semiconductor surface layer, wherein the step of growing the epitaxial layer structure on the substrate is performed such that a lattice mismatch Δω of the multiple-quantum well with respect to the substrate satisfies a range of −0.13%≦Δω
