SBIR Phase I: Large Diameter CdS Single Crystal Substrates for II-VI-based Light Emitters and Displays

这个小企业创新研究（SBIR）第一阶段项目将展示一种新的晶体生长技术，用于批量生产大直径、高质量的硫化镉（cd）单晶，适合作为制造ii - vi基发光器件的晶格匹配衬底，特别是ZnCdMgSe量子阱发光器件和高分辨率全彩显示器。开发高性能ZnCdMgSe量子阱发光器件的一个挑战是克服晶格匹配、大直径和高质量CdS单晶衬底的制造障碍。本研究将研究一种独特的生长技术，以有效的方式生产大直径、高质量的CdS单晶，从而以具有竞争力的价格生产大直径CdS单晶衬底。如果所提出的生长技术成功地用于量产，大直径、高质量的cd单晶衬底将以可承受的价格广泛商业化，这将大大加速高性能ii - 6基发光器件和基于led的全彩显示器的开发和商业化，用于各种国防、工业和商业应用。公司相对于竞争对手的优势在于生产大直径单晶的经验和高效制造工艺的开发。

This Small Business Innovation Research (SBIR) Phase I project will demonstrate a novel crystal growth technique for volume production of large diameter, high quality cadmium sulfide (CdS) single crystals suitable as lattice-matched substrates for fabricating II-VI-based light emitters, particularly ZnCdMgSe quantum-well light emitting devices and high resolution full-color displays. One challenge in the development of high-performance ZnCdMgSe quantum-well light emitting devices is the overcoming of manufacturing hurdles of lattice-matched, large-diameter and high-quality CdS single crystal substrates. The proposed effort will investigate a unique growth technique for producing large-diameter, high-quality CdS single crystals in an efficient manner, so that large diameter CdS single crystal substrates may be manufactured at a competitive price. If the proposed growth technology is successfully adopted in volume production, large-diameter, high-quality CdS single crystal substrates will become widely available commercially at an affordable price, which will greatly accelerate development and commercialization of high-performance II-VI-based light emitters and LED-based full-color displays for varieties of defense, industrial and commercial applications. The company's advantage over the competitors is the experience in producing large diameter single crystals and development of an efficient manufacturing process.
