9604915 Wu This award supports cooperation between Yue Wu and Daxing Han, University of North Carolina, Chapel Hill, and Kong Guanglin, Institute of Semiconductors, Chinese Academy od Sciences, Beijing, on the role of hydrogen in the metastability of hydrogenated amorphous silicon. The research problem is an important one that has not been satisfactorily addressed despite much research over the years. The investigators propose a joint study of infrared absorption and nuclear magnetic resonance to explore the metastable photostructural effects associated with extended illumination. The Chinese group has recently published results that are somewhat controversial; cooperation in further research in this area will allow the US team to advance current understanding by attempting to replicate results on other samples of amorphous silicon produced by other growth techniques. Advances in this research could contribute to improved technology in both photovoltaics and flat-panel displays. This project is jointly supported by NSF and the Chinese Academy of Sciences and the National Natural Science Foundation of China.

9604915吴该奖项支持吴岳与北卡罗来纳大学教堂山分校的韩大兴以及中国科学院半导体研究所的孔广林就氢在氢化非晶硅亚稳态中的作用进行的合作。研究问题是一个重要的问题，尽管多年来进行了大量的研究，但仍未得到令人满意的解决。研究人员提出了红外吸收和核磁共振的联合研究，以探索与扩展照明相关的亚稳态光结构效应。这个中国研究小组最近发表的研究结果有些争议；在该领域的进一步研究合作将使美国团队通过尝试在其他生长技术生产的非晶硅的其他样品上复制结果来推进当前的理解。这项研究的进展将有助于提高光伏技术和平板显示技术。本项目由美国国家科学基金会、中国科学院和国家自然科学基金共同支持。
