强量子限制iii -氮化物材料系统从根本上为可扩展半导体腔量子电动力学提供了在高温（200K或更高）下工作的独特机会。在材料生长、光谱学和第一性原理建模的支持下，本研究探讨了InGaN量子点与介观光学腔的结合，用于固态腔量子电动力学。对材料生长和器件纳米加工进行了优化，以实现低缺陷密度生长。单量子点的目标是光发射及其修饰，以及非经典光学。这项研究结合了两个小组的专业知识：新加坡材料研究与工程研究所（IMRE）的iii -氮化物材料生长和哥伦比亚大学的光学表征和光子晶体。将对器件的激子特性进行光学探测。微腔，如窃窃私语廊模式和光子带隙腔将被检查。这个材料世界网络项目使美国和新加坡科学家之间的重要互补努力成为可能，为研究生和高级科学家在不同的工作环境中提供宝贵的经验。这种合作也为固态物理和量子信息处理领域的未来努力奠定了基础。该研究还与国际教育和交流工作相辅相成，包括两个机构在材料生长和光谱学方面的反复反馈和互动，博士生的共同指导，美国人员的国际参与以及高级研究人员的交流。此外，还支持高中教师和本科生交流。为了支持这项国际活动，还举行了视像电话会议审查。在这个合作项目中开展的研究将在网络上以及通过国际会议和出版物进行传播。

The strongly quantum-confined III-nitride material system fundamentally offers the distinct opportunity to operate at high temperatures (200K or more) for scalable semiconductor cavity quantum electrodynamics. Supported by advances in materials growth, optical spectroscopy, and first-principles modeling, this research examines the combination of InGaN quantum dots with mesoscopic optical cavities for solid-state cavity quantum electrodynamics. Optimization of the materials growth and device nanofabrication is performed, to examine low defect density growth. Single quantum dots are targeted for light emission and its modification, as well as nonclassical optics. This research combines the expertise of two groups: III-nitrides materials growth at the Institute of Materials Research and Engineering (IMRE) in Singapore, and optical characterization and photonic crystals at Columbia University. The devices will be optically probed for the exciton characteristics. Microcavities such as whispering gallery modes and photonic band gap cavities will be examined. This Materials World Network project enables critical complementary efforts between scientists in the United States and Singapore, providing invaluable experience to the graduate students and senior scientists in different working environments. This collaboration also seeds future efforts in the area of solid-state physics and quantum information processing. This research is complemented with international education and exchange efforts, involving iterated feedback and interactions between the two institutions on materials growth and optical spectroscopy, co-supervision of PhD students, participation of the US personnel internationally, and exchange of senior research staff. Furthermore, high-school teacher and undergraduate student exchanges are supported. To support this international activity, video teleconference reviews are also held. The research developed in this collaborative program will be disseminated on the web as well as through international conferences and publications.
