Patent number: 6940100Abstract: A semiconductor light-emitting device of Group III-V compound semiconductors includes a quantum well layer, which is formed over a substrate and includes a barrier layer and a well layer that are alternately stacked one upon the other. The band gap of the well layer is narrower than that of the barrier layer. The well layer contains indium and nitrogen, while the barrier layer contains aluminum and nitrogen. In this structure, a tensile strain is induced in the barrier layer, and therefore, a compressive strain induced in the quantum well layer can be reduced. As a result, a critical thickness, at which pits are created, can be increased.Type: GrantFiled: January 3, 2003Date of Patent: September 6, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Ayumu Tsujimura, Yoshiaki Hasegawa, Akihiko Ishibashi, Isao Kidoguchi, Yuzaburo Ban, Masakatsu Suzuki
