We propose to experimentally investigate MOCVD (Metal Organic Chemical Vapor Deposition) as a technique for growing high-quality Type-II InAs/(In)GaSb SLS (Strained Layer Superlattice) photodiode epi material. In collaboration with the University of Maryland, our goal is to grow, process, and measure longwave infrared detector material and devices and compare them to identical MBE (Molecular Beam ...

In Phase I, we will demonstrate a dualband InAs/GaSb strained layer superlattice (SLS) photodiode with bias-selectable 3-5 and 8-12 micron spectral response. Bandgap engineering will be used to minimize dark current and make array processing simple and robust with the goal of demonstrating a prototype dualband focal plane array (FPA) in the Phase I Option itself. In Phase II, we will optimize FPA ...

Solid State Scientific Corporation (SSSC) is pleased to propose a Phase I SBIR program to develop a unique spectral imaging sensor prototype based on micro-optics with a COTS astronomical camera. The micro-optic separates the image into spectral views of the image that are spatially and temporally registered. The proposed approach has been demonstrated on a telescope to simultaneously image space ...

In this NAVY SBIR Phase I program, we propose a radio frequency (RF) direction finding sensor for low probability of intercept (LPI) RF radar system. This sensor consists of a dielectric fisheye lenses and an innovative focus plane detector array (FPDA). The fisheye lenses, as a RF antenna, have been broadly used in camera and electronic-optical systems (from visible to infrared wavelength). In th ...

This Small Business Innovation Research (SBIR) Phase I project aims to develop novel field detectors and memory devices capable of detecting magnetic field of an electromagnetic pulse (EMP). The sensor is made of magnetic nanowire arrays consisting of magnetic nanowires embedded in an insulating matrix, and is able to memorize the incoming rf magnetic field pulse as short as 100ps and survive in a ...

We propose to provide essential protection from lacerations, punctures and abrasion for SOCOM’s free swimming diver force using a multi-layer laminate. The key technology will employs a novel stretch-pleat design with a proven puncture and cut resistant fabric that will allow a lower diving mass ensemble with a focus on mobility. The core puncture and cut layer is based on a lightweight punctur ...

Spire Semiconductor proposes a novel MOCVD growth scheme that will substantially reduce the production costs of inverted multi-junction solar cells. Incorporating quantum well structures will be investigated as a means to improve device efficiency and end of life cell performance in the space environment. The theoretical target efficiency is 39.8% under the AM0 spectrum.

Dark current plays an essential role in the performance of LWIR InAs/GaSb SL-based FPAs. Previous improvements in material quality and device design have significantly suppressed bulk contributions to the dark current. The dark current due to surface defects becomes prominent with decreasing detector size, as in the case of high-resolution FPAs. Furthermore, for LWIR FPA with very small band gap e ...

Spire Semiconductor proposes to make InAs/GaSb based MWIR/LWIR dual-band FPA photodetectors with low surface-leakage current using the unique processing and passivation techniques developed at Spire Semiconductor. In phase I, Spire Semiconductor will demonstrate FPA pixel-sized (~30x30um-2) dual-band (5 um cutoff for MWIR and 10 um cutoff for LWIR) photodetectors and small array (320x256) with 77K ...

DESCRIPTION (provided by applicant): The HIV-1 epidemic has resulted in ~2.7 million new infections in 2007 for a total of ~33 million people living with HIV/AIDS. Clinical trials have shown that HIV-1 infection cannot be prevented by immunization with monomeric recombinant forms of viral envelope (Env) proteins. However, it is clear that the HIV-1 Env contains epitopes that can induce neutralizin ...
