Local Bonding and Properties of Cr-Oxycarbonitrides Using Scanning Tunneling and Optical Spectroscopies

9531743 Bonnell本研究项目旨在了解化学分级的碳氮化铬薄膜的局部变化对薄膜性能的影响。这笔赠款是由Goali倡议支持的，是宾夕法尼亚大学和杜邦公司的研究人员共同努力的成果。它计划利用样品组成中精确和充分表征的变化来关联电子结构、电荷密度、介电性质和光学性质。提出的主要实验研究工具是扫描隧道和光学光谱以及更标准的表征方法(SIMS、RBS、EDS等)。该项目的一个主要目标是获得足够的基础知识，以开发一个将局部成键与多组分体系中的性质联系起来的模型。该项目的一个重要特点是通过为学生提供在大学和工业研究环境中进行基础材料科学研究的宝贵机会，将研究和教育相结合。这些学生将接受宾夕法尼亚大学的邦内尔教授和杜邦的弗兰奇博士的联合指导。将建立一个计算机网络连接，使两个地点的实验数据和模型可以在另一个地点访问；该网络还将包括一个用于信息交换的公告牌。该项目代表了学术界和产业界之间强大的研究联盟，同时通过在一个具有根本和技术意义的领域对学生进行培训，为教育和研究的整合提供了一个有吸引力的安排。***

9531743 Bonnell This research project seeks to understand the effects of local variations in chemically graded Cr-oxycarbonitride films on film properties. This grant, which is supported under the GOALI initiative, is a collaborative effort between researchers at the University of Pennsylvania and DuPont. It is planned to use precise and well characterized variations in sample composition to correlate electronic structure, charge density, dielectric properties, and optical properties. The principal experimental research tools proposed are scanning tunneling and optical spectroscopies along with more standard characterization methods (SIMS, RBS, EDS, etc.). A major goal of the project is to achieve sufficient fundamental knowledge to develop a model relating local bonding to properties in multicomponent systems. %%% An important feature of the program is the integration of research and education by provision of an invaluable opportunity for students to conduct fundamental materials science research in both University and Industrial research environments. The students will receive joint mentoring by Prof.Bonnell/University of Pennsylvania, and Dr. French/DuPont. A computer network connection will be established to allow experimental data and modeling at either location to be accessed at the other; the network will also include a bulletin board for information exchange. The project represents a strong research alliance between academia and industry, and at the same time provides an attractive arrangement for integration of education and research through the training of students in a fundamentally and technologically significant area. ***
