U.S.-Saudi Arabia Workshop on Photonics Technology for Advanced Energy Conservation, Thuwal, Saudi Arabia, November 2010

denbaars该项目支持将于2010年11月在沙特阿拉伯图瓦尔的阿卜杜拉国王科技大学（KAUST）举行的“美国-沙特阿拉伯先进节能光子学技术研讨会”。美国组织者是加州大学圣巴巴拉分校的Steven P. DenBaars博士。沙特的组织者是KAUST材料科学与工程教授Iman Rogan博士。研讨会的目的是确定美沙联合提案的合作领域。研讨会将为处于节能照明前沿的美国科学家与KAUST和沙特阿拉伯其他大学的教师之间的互动提供一个论坛。KAUST成立了“太阳能与替代能源科学与工程研究中心”，其重要使命是支持与国外研究的合作。它还计划建立一个“先进光子学技术中心”，具有与国外研究人员合作的类似使命。研讨会还将帮助指导科大先进光子学技术中心的研究活动。为期三天的研讨会将讨论实现输出大于300流明/瓦的全半导体白光光源所需的基本材料科学和工程问题，对应于大于85%的插头效率。在研讨会的最后半天，参与者将被要求为KAUST的先进光子学技术中心提出方向，并提出与KSA内的教职员工的工作关系，以指导拟议的研究项目。所有照明消耗了超过20%的电力，相当于超过25 Quads的初级燃料（相关的4.1亿吨碳排放），每年的成本接近3000亿美元。传统的照明光源包括白炽灯和荧光灯，它们在将电转换为光方面效率低下，即白炽灯为2-4%（7-15流明/瓦（lm/W）），荧光灯为15-20%（50-80流明/瓦）。研讨会的主题是通过集中研究固态照明材料的关键领域来改善这种低效率。预计固态照明方法将实现85%的能源效率，相应的光效超过300流明/瓦，并且能够完全依靠太阳能或风能等可持续能源。此外，固态光源提供几乎无限的场寿命（例如，25-50年）。本次研讨会的成果和拟议的研究将指向基于氮化镓的发光二极管（led）科学，这是最终将取代现有照明技术的最终照明光源。知识优势：研讨会将讨论以下领域：非极性和半极性LED器件；光设备;无缺陷体GaN晶体，用于固态白光和节能光子器件和系统的荧光粉。这些都是开发节能照明系统和设备的前沿课题。在美国开展的工作是世界上最先进的，但可以从与新的和即将成立的机构的物质和人力资源的互动和合作中受益，这些机构可以扩大这一重要领域的工作，这对全世界都有好处。更广泛的影响：研讨会的结果可能会导致几个美国机构与沙特阿拉伯和其他中东地区的领先大学之间的合作，这可能会对如何提供照明和照明的能源消耗产生重大影响。这项工作可以通过控制能源消耗对环境产生重大影响。计划有10名美国高级科学家和6名美国初级科学家以及4名美国博士后参加。还邀请了来自沙特阿拉伯王国（沙特阿拉伯）和中东的10名与会者。

DenBaarsThis project supports a "US-Saudi Arabia workshop on Photonics Technology for Advanced Energy Conservation" to be held at King Abdullah University for Science and Technology (KAUST) in Thuwal, Saudi Arabia in November 2010. The US organizer is Dr. Steven P. DenBaars, University of California-Santa Barbara. The Saudi organizer is Dr. Iman Rogan, Professor of Material Science and Engineering at KAUST. The objective of the workshop is to identify areas for collaboration that will lead to joint US-Saudi proposals. The workshop will provide a forum for interaction between US scientists who are at the leading edge of lighting for energy conservation, and the faculty at KAUST and other universities in Saudi Arabia. KAUST has established a "Solar and Alternative Energy Science and Engineering Research Center" with a significant mission to support collaboration with researches abroad. It also plans to establish a "Center for Advanced Photonics Technology", with a similar mission for collaboration with researchers abroad. The workshop will also help direct the research activities for that Center for Advanced Photonics Technology at KAUST. The three day workshop will address the basic materials science and engineering issues required to achieve an all semiconductor-based white-light source with an output greater than 300 lumens/watt, corresponding to greater than 85% wall-plug efficiency. The last half day of the workshop, participants will be asked to proposed directions for the Center for Advanced Photonics Technology at KAUST and propose a working relation with faculty within the KSA leading to proposed research projects.All lighting consumes over 20% of all electricity produced which corresponds to over 25 Quads of primary fuel (with an associated 410 million tons of carbon emissions), at an annual cost approaching $300 billion. Conventional lighting sources include incandescent lamps and fluorescent lamps, which are inefficient at converting electricity to light, i.e., 2-4% (7-15 lumens/watt (lm/W)) for incandescent, and 15-20% (50-80 lm/W) for fluorescent. The workshop topics seek to ameliorate this inefficiency by focusing research efforts in key areas of materials for solid-state lighting. It is expected that the solid state lighting approach will achieve 85% energy efficiency, with a corresponding luminous efficacy of over 300 lumens/watt, and be able to run entirely off sustainable energy sources such as solar or wind. Solid state lighting sources, in addition, offer nearly an infinite field lifetime (e.g., 25-50 years). The outcome of this workshop and the proposed research will be directed towards the science of Light Emitting Diodes (LEDs) based on GaN, the ultimate lighting source that will eventually replace existing lighting technologies.Intellectual Merits: The workshop will discuss areas of: Non-polar and semi-polar LED devices; light devices; defect free bulk GaN crystals, phosphors for solid-state white lighting and energy efficient photonic devices and systems. These are among the cutting edge topics in developing energy efficient lighting systems and devices. The work carried out in the US is among the most advanced in the world, but can benefit from interactions and collaborations with new and upcoming institutes with material and human resources that can expand the work in this important area, which has world-wide benefit.Broader Impacts: The results of the workshop may lead to collaboration between several US institutions with leading Saudi and other Middle East universities in an area that can have a very significant impact on how lighting is provided, and the energy consumption for that lighting. The work can have significant environmental impact by curbing energy consumption. It is planned that 10 senior and 6 junior US scientists, as well as four US post-docs, will participate. Ten participants from within the Kingdom of Saudi Arabia (KSA) and in the Mid-East have also been invited.
