U.S.-India Cooperative Research: Photoinduced Degradation in Doped Hydrogenated Amorphous Silicon, Award in US and Indian Currency

描述：“掺杂氢化非晶硅（a- silh）的光诱导降解”是犹他大学Craig Taylor教授和德里大学P.C. Mathur教授和R.M. Mahra教授在材料研究方面的合作。这一提议为泰勒教授在无序半导体和薄膜光伏材料特性方面的研究增加了国际成分。Taylor在理解金属硫系玻璃是连接四面体配位非晶态材料和传统硫系玻璃的模型体系方面取得了重大进展。作为逻辑延伸，本提案将集中于n型掺杂硅硫合金的光诱导降解和输运性质。范围：这是一个连接美国和印度两所大学研究实验室的新合作。该研究旨在了解对太阳能电池最佳性能至关重要的a-Si:H中的亚稳态缺陷。这项研究结合了美国在增长、光学和磁共振表征方面的专业知识，以及印度在运输和结构测量方面的专业知识。该研究计划旨在最终提高薄膜晶体管和太阳能电池等设备的稳定性。＊＊＊

9634604 Taylor Description: The proposed research "Photoinduced Degradation in Doped Hydrogenated Amorphous Silicon (a-SiLH)" is a collaboration in materials research between Professor Craig Taylor, University of Utah and Professors P.C. Mathur and R.M. Mahra, University of Delhi. This proposal adds an international component to Professor Taylor's research on the properties of disordered semiconductors and thin-film photovaltaic materials. Taylor has made significant progress in understanding metal chalcogenide glasses as a model system linking tetrahedrally-coordinated amorphous materials and traditional chalcogenide glasses. As a logical extension, this proposal will concentrate on photo-induced degradation and transport properties of n-type doped silicon- sulfur alloys. Scope: This is a new collaboration linking two university research laboratories in the US and India. The research seeks to understand metastable defects in a-Si:H that are crucial for optimum performance of solar cells. The research combines US expertise on growth, optical and magnetic resonance characterization and Indian expertise on transport and structural measurements. The research plan is designed to make progress on ultimately improving the stability of devices such as thin-film transistors and solar cells. ***
