  • Method for wafer bonding (A1, In, Ga)N and Zn(S, Se) for optoelectronic applications
    Patent number: 7344958
    Abstract: A method for producing a wafer bonded structure between (Al, In, Ga)N and Zn(S,Se). A highly reflective and conductive distributed Bragg reflector (DBR) for relatively short optical wave lengths can be fabricated using Zn(S,Se) and MgS/(Zn, Cd)Se materials. Using wafer bonding techniques, these high-quality DBR structures can be combined with a GaN-based optical device structure.
    Type: Grant
    Filed: July 6, 2005
    Date of Patent: March 18, 2008
    Assignees: The Regents of the University of California, Universitaet Bremen, Japan Science and Technology Agency
    Inventors: Akihiko Murai, Lee McCarthy, Umesh K. Mishra, Steven P. DenBaars, Carsten Kruse, Stephan Figge, Detlef Hommel
