NIPI superlattices in InSb: an alternative route to 10 mu m detector fabrication

Preliminary experimental spectral photoconductivity, time-resolved photoconductivity and non-linear optical absorption data are presented which demonstrate that NIPI structures have been produced in InSb for the first time. The measured band gap reduction and lifetime enhancement effects are in excellent agreement with the predictions of the authors' theoretical model and indicate a clear potential for these structures as high-performanceIR detectors.
