SBIR Phase II: Zinc Selenide Substrates and Blue-Green Laser Diodes

9531283 Chu该项目解决了基于ZnSe的蓝绿色LED和激光二极管开发中的关键衬底问题。 近年来，由于ZnSe基LED和激光二极管在显示器、电子、通信和信息存储等领域的巨大市场潜力，人们对ZnSe基LED和激光二极管的开发产生了极大的兴趣。 在所有的半导体中，ZnSe是唯一一种用于产生蓝绿色激光的半导体。 然而，蓝光激光器的寿命已成为一个关键问题。 据信，寿命不足的原因是缺乏器件质量、晶格匹配的ZnSe衬底。 一种创新的技术（PPCVPT）生长ZnSe晶体将被使用。 科学上，该项目将证明p型ZnSe可以通过最大限度地减少原生缺陷来生产。用于生产ZnSe激光器的2英寸ZnSe将商业化。 在哥伦比亚大学分子束外延能力的帮助下，该项目还将生产ZnSe激光二极管。 将测试在ZnSe衬底上生长的ZnSe激光器的可靠性。 测试结果将用于改善ZnSe衬底的质量。

9531283 Chu This project addresses the critical substrate issue in the development of ZnSe based blue-green LEDs and laser diodes. Recently, there has been much interest in the development of ZnSe based LEDs and laser diodes due to the tremendous market potential for their applications in displays, electronics, communications and information storage. Among all the semiconductors, ZnSe is the only one which has been used to produce blue-green lasers. However, the lifetime of the blue lasers has become a critical issue. It is believed that the cause of the insufficient lifetime is the lack of device quality, lattice-matched ZnSe substrates. An innovative technique (PPCVPT) to grow ZnSe crystals will be used. Scientifically, the project will demonstrate that p-type ZnSe can be produced by minimizing the native defects. Two inch ZnSe for producing ZnSe lasers will be commercialized. ZnSe laser diodes will also be produced in this project with the assistance of MBE capability at Columbia University. The reliability of ZnSe lasers grown on ZnSe substrates will be tested. Testing results will be used to improve the quality of the ZnSe substrates.
