SEMICONDUCTOR LIGHT-EMITTING ELEMENT AND METHOD OF PRODUCING SEMICONDUCTOR LIGHT-EMITTING ELEMENT

원문 (중국어)

Provided is a semiconductor light-emitting element having good light emission characteristics compared to conventional light-emitting elements. The semiconductor light-emitting element includes a light-emitting layer including a laminate in which first and second III-V compound semiconductor layers are stacked repeatedly. Group III element in the first and second III-V compound semiconductor layers is one type or two or more types selected from the group consisting of Al, Ga, and In. Group V element in the first and second III-V compound semiconductor layers is one type or two or more types selected from the group consisting of As, Sb, and P. A composition wavelength difference between composition wavelengths of the first and second III-V compound semiconductor layers is 70 nm or more. In a band structure of the laminate, conduction band-side well depth (Dc) is larger than valence band-side well depth (Dv), and Dc/(Dc+Dv) is 65% or more.
