Reactions of Silanes with Coordinated Ligands: Mechanistic Studies of Molecular Routes to Metal Silicides

化学部无机、生物无机和有机化学项目的这一奖项授予诺克斯维尔田纳西大学化学系的薛子凌（本）博士，他研究了硅烷与配位酰胺、烷基、无机和有机金属化合物中的亚烷基和亚烷基炔，例如（i）阐明金属硅化物制备中的反应性质和机理途径，（ii）用这些配体合成新的过渡金属硅衍生物，以及（iii）开发新的化学气相沉积工艺以制造金属硅化物。除了化学气相沉积工艺的开发之外，具有金属硅化物结构特征的金属簇将被制备以获得将导致更好的分子设计的见解。现有的和新的硅化物基固态材料的路线。这些材料是超大规模集成器件以及高温和红外探测器系统的重要组成部分。学生和博士后助理将在合成化学和材料科学的专业知识和国家的最先进的设施，将促进和加强田纳西大学诺克斯维尔和橡树岭国家实验室之间的合作环境中进行培训。

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division is made to Dr. Ziling (Ben) Xue of the Chemistry Department of the University of Tennesseee, Knoxville, to study reactions of silanes with coordinated amides, alkyls, alkylidenes and alkylidynes in inorganic and organometallic compounds so as (i) to elucidate the nature of the reactions and the mechanistic pathways in the preparation of metal silicides, (ii) to synthesize new transition-metal silicon derivatives with these ligands, and (iii) to develop novel chemical vapor deposition processes to fabricate metal silicides.In addition to the development of chemical vapor deposition processes, metal clusters that possess the structural features of metal silicides will be prepared to gain insights that will lead to better designs of molecular routes to existing and new silicide-based solid-state materials. These materials are important components in very-large-scale-integration devices, and in high-temperature and infrared detector systems. Students and post-doctoral associates will be trained in synthetic chemistry and materials science in an environment of expertise and state-of-the-art facilities that will foster and enhance collaboration between the University of Tennessee at Knoxville and Oak Ridge National Laboratory.
