nBn Based Dual-Band Focal Plane Arrays with Type II InAs/GaSb Superlattices Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-012 Topic Title: nBn Based Dual-Band Focal Plane Arrays with Type II InAs/GaSb Superlattices Proposal No.: N101-012-0845 Firm: SK Infrared LLC Lobo Venture Lab 801 University Blvd Ste Albuquerque, New Mexico 87106-4345 Contact: Sanchita Krishna Phone: (505) 504-6846 Web Site: www.skinfrared.com Abstract: SK Infrared LLC, a spin-off from the Krishna INfrared Detector (KIND) laboratory at the UNM (www.chtm.unm.edu/kind) is proposing to develop a dual band SLS based imager using an nBn based heterostructure design in collaboration with Raytheon Vision Systems (letter attached). The proposed effort leverages the technical expertise and facilities of only one of the two university laboratories in the world that has demonstrated "Epi to Camera" research. The Krishna group has a successful track record in the design, growth, fabrication and characterization of SLS FPAs. UNM has agreed to let SK Infrared LLC use the facilities at CHTM (letter attached) for this effort. This will include access to a brand-new VEECO Gen-10 MBE reactor. The Krishna group has demonstrated the first SLS based nBn single pixel detector and 320x256 focal plane arrays with an NETD=24mK. Moreover, by engineering the bandgaps of the absorber on either side of the barrier, the Krishna group has demonstrated a dual band nBn detector. Prof. Krishna also has close ties with DoD agencies such as Army Night Vision Laboratory and is a part of the user group that provides feedback to FLIR for the new dual polarity ROIC as a part of MDA''S FastFPA program Benefits: The business plan of SK Infrared LLC revolves around the generation of high performance dual band infrared focal plane arrays for medical diagnostics. For example, one of the applications could be in the early diagnosis of melanoma or skin cancer. It is estimated that over 1 million people are diagnosed with skin cancer every year For these patients, who observe a mole or nevus on their body, there are two options to determine if the mole is malignant or benign. The first is to undertake a subjective and sometimes inaccurate ABCDE test, which consists of determining the Asymmetry, Border, Color, Diameter and Elevation of the mole. The second is to undergo an invasive surgical biopsy of the removed tissue. SK infrared LLC aims to incubate a technology based on the temporal response of the temperature of the nevus to develop a non-invasive diagnostic tool using infrared imaging. It is estimated that the thermography market alone is about $550M with a 22% growth rate in the past five years. We expect to incubate the technology for 3-5 years and develop high performance superlattice FPAs for this market Return
