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Thuwal的阿卜杜拉国王科技大学（KAUST）举办的“美国-沙特阿拉伯先进节能光子技术研讨会”。 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合作领域，从而提出美国和沙特的联合建议。该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成立了一个“太阳能和替代能源科学与工程研究中心”，其重要的使命是支持与国外研究的合作。 它还计划建立一个“先进光子技术中心”，具有与国外研究人员合作的类似使命。该研讨会还将帮助指导KAUST先进光子技术中心的研究活动。 为期三天的研讨会将讨论基本的材料科学和工程问题，以实现输出大于300流明/瓦的全基于半导体的白光源，对应于大于85%的壁插效率。在研讨会的最后半天，与会者将被要求为KAUST的先进光子技术中心提出方向，并提出与KSA内的教师的工作关系，从而导致拟议的研究项目。所有照明消耗超过20%的电力生产，相当于超过25夸脱的主要燃料（相关的碳排放量为4.1亿吨），每年的成本接近3000亿美元。传统的照明源包括白炽灯和荧光灯，它们在将电转换为光方面效率低，即，白炽灯2-4%（7-15流明/瓦（lm/W）），荧光灯15-20%（50-80 lm/W）。研讨会的主题旨在通过将研究工作集中在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，相应的发光效率超过300流明/瓦，并且能够完全依靠太阳能或风能等可持续能源运行。 此外，固态照明源提供几乎无限的场寿命（例如，25-50岁）。本次研讨会的成果和拟议的研究将针对基于GaN的发光二极管（LED）的科学，最终将取代现有的照明技术的最终光源。知识优势：研讨会将讨论的领域：非极性和半极性LED器件;照明器件;无缺陷块状GaN晶体、固态白色照明用磷光体以及节能光子器件和系统。 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工作之一，但可以受益于与新的和即将成立的机构的互动和合作，这些机构拥有物质和人力资源，可以扩大这一重要领域的工作，这对世界各地都有好处。研讨会的结果可能会导致几个美国机构与沙特和其他中东领先大学在一个领域的合作，可以对如何提供照明以及该照明的能量消耗产生非常显著的影响。 这项工作可以通过抑制能源消耗来对环境产生重大影响。 计划有10名美国高级科学家和6名初级科学家以及4名美国博士后参加。还邀请了沙特阿拉伯王国和中东的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.
