U.S.-China Cooperative Research: The Role of Hydrogen in the Metastability of Hydrogenated Amorphous Silicon: NMR and DIR Studies

小行星9604915 该奖项支持吴跃和北卡罗来纳州查佩尔山大学的韩大兴以及中国科学院半导体研究所的孔广林在氢化非晶硅亚稳态中的作用方面的合作。 研究问题是一个重要的问题，尽管多年来进行了大量研究，但尚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，以探索与延长照明相关的亚稳态光结构效应。中国团队最近发表了一些有争议的结果;在这一领域进一步研究的合作将使美国团队能够通过尝试复制其他生长技术生产的非晶硅样品的结果来推进当前的理解。 这项研究的进展可能有助于改善光电子学和平板显示器的技术。 该项目由NSF和中国科学院及国家自然科学基金共同资助。

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.
