99--TECHNOLOGY TRANSFER OPPORTUNITY X RAY DIFFRACTION METHOD FOR DEFECTCHARACTERIZATION OF EPITAXIALLY GROWN CUBIC SEMICONDUCTOR LAYERS

NASA Langley Research Center in Hampton, VA solicits interest from companiesinterested in obtaining license rights to commercialize, manufacture and market thefollowing technology. License rights may be issued on an exclusive or nonexclusive basisand may include specific fields of use. THE TECHNOLOGY: NASA Langley researchers have developed a novel semiconductor epitaxial growth andcharacterization technology for rhombohedrally aligned cubic semiconductors on trigonalcrystal substrates. Several important semiconductor materials are potentially affected bythis technology, including cubic semiconductor alloys of Group IV materials such assilicon (Si), germanium (Ge), carbon (C) and its alloy SiGe, Group III-V materials suchas gallium arsenide (GaAs) andgallium phosphate (GaP), and Group II-VI materials such as zinc selenide (ZnSe) andcadmium telluride (CdTe) on various new trigonal substrates. Many of these semiconductormaterials are being used or developed for a number of high power, high frequency, opticalfiber communication, far-infrared imaging, and high temperature device applications,including cellular communications as one example. This characterization method enablesmapping of defect density and defect location, allowing optimization of growth processparameters forfabricating high-quality, defect-free semiconductor devices.To express interest in this opportunity, please respond to Sean Sullivan, ResearchTriangle International (RTI), at: NASA Langley Research Center, Strategic RelationshipsOffice (SRSO), 17 West Taylor St., Mail Stop 218, Building 1212, Room 110 Hampton,Virginia, E-mail: contact@example.gov, or phone: +1 (555) 000-0000. Please indicate thedate and title of the FBO notice and include your company and contact information.RTI is responsible for aggregating and acknowledging all responses. These responses areprovided to members of NASA Langleys Innovative Partnerships Office within the SRO forthe purpose of promoting public awareness of our technology products, and conductingpreliminary market research to determine public interest in and potential for futurelicensing opportunities. If direct licensing interest results from this posting, SRO willfollow the formal licensing process of posting in the Federal Register as required. Nofollow-on procurement is expected to result from responses to this Notice.
