ABSTRACT:
An epitaxial wafer for a light-emitting diode comprises an n-GaAs single crystal substrate on which a Si-doped n-Ga.sub.1-x Al.sub.x As epitaxial layer, a Si-doped p-Ga.sub.1-y Al.sub.y As active layer, and a p-Ga.sub.1-z Al.sub.z As window layer are epitaxially formed, and in which the window/layer has a Si concentration of below 1.times.10.sup.18 cm.sup.-3.
