  • Radiation-emitting semiconductor component
    Patent number: 7042013
    Abstract: A radiation-emitting semiconductor component having a layer structure which contains an n-doped cladding layer (18), a p-doped cladding layer (20), and an active layer (14) based on InGaAlP arranged between the n-doped cladding layer (18) and the p-doped cladding layer (20). A diffusion stop layer (16) is arranged between the active layer (14) and the p-doped cladding layer (20). The diffusion stop layer (16) is formed by a strained superlattice.
    Type: Grant
    Filed: August 22, 2003
    Date of Patent: May 9, 2006
    Assignee: Osram Opto Semiconductors GmbH
    Inventors: Norbert Linder, Peter Stauss, Mark Hampel, Klaus Streubel
