This award is for the renewal of the Materials Research Group at Case Western University on the topic of low pressure growth of diamond and diamond-like materials. The principal experimental program areas are: (1) studies of the nucleation and growth of diamond and diamond-like materials including the nature of the molecular precursors, the origin and role of defects during growth, and heteroepitaxial growth, (2) fundamental structural and property measurements including mechanical properties, transport properties, influence of doping and hydrogen. The theoretical studies include: (1) molecular orbital studies of nucleation and growth, (2) electronic structure calculations of interfaces and surfaces, (3) Monte Carlo computer modelling of growth, and (4) reactor modelling. The diamond and diamond-like films are characterized using ion beam analysis, electron microscopy, Fourier transform nuclear magnetic resonance, Fourier transform infrared spectroscopy, x-ray diffraction, and Raman scattering. The experimental and theoretical efforts are highly interactive.

该奖项是针对Case Western University材料研究小组的续签，讨论钻石和类似钻石的材料的低压生长。 主要实验程序领域是：（1）研究钻石和类似钻石的材料的成核和生长，包括分子前体的性质，在生长过程中缺陷的起源和作用以及杂产生的生长，（2）基本结构和特性，包括机械性能，运输特性，运输特性，档案和水力的影响。 理论研究包括：（1）成核和生长的分子轨道研究，（2）接口和表面的电子结构计算，（3）蒙特卡洛计算机的生长计算机建模以及（4）反应器建模。 使用离子束分析，电子显微镜，傅立叶变换核磁共振，傅里叶变换红外光谱，X射线衍射和拉曼散射来表征钻石和钻石样膜。 实验和理论上的工作是高度互动的。
