Type II Superlattice vs. MCT Accomplishments
(1625µm)

• Spectral response of photodiodes with different
  InAs/GaSb superlattices in their active layer.
  The thickness of GaSb layer is 40Å for all of the
  superlattices, while the thickness of the InAs
  layer is shown for each device. The 90-10
  cutoff energies of all of the devices are bellow
  2kT. (Proc. SPIE-Int. Soc. Opt. Eng. (2001),
  4288, 191-199)

Superlattice Modeling
Characterization

• AFRL/MLPS used superlattice design models to
  guide SL growth and verify the performance of the
  SL as an infrared detector material.
• Success in-house and collaborations with
  University of Houston and Northwestern University
  led to the first demonstration of Very Long
  Wavelength Infrared Detector.
• In FY02, a 6.2 contract was initiated by
  AFRL/MLPS to transition these materials to the IR
  industry.
