  • Method for improvement of optical quality and reduction of background doping in gainSB/INAS superlattices
    Patent number: 5451552
    Abstract: Post-growth annealing of GaInSb/InAs superlattices at about 400.degree. to 650.degree. C. in an antimony flux followed by cooling results in enhanced optical properties as determined by photoluminescence and in reduced background doping levels as determined by Hall measurements. Accordingly, the annealing procedure represents an advantage over previous fabrication techniques for Ga.sub.1-x In.sub.x Sb/InAs superlattices.
