AbstractCHE-0616873Fairbrother/Johns HopkinsWith the support of the Analytical and Surface Chemistry Program, Professor Fairbrother and his colleagues at the Johns Hopkins University are studying the kinetics and morphology of the growth of hydrogenated amorphous carbon nitride films. A model plasma reactor, consisting of a methyl radical source and hydrogen and nitrogen ion sources, is used to controllably grow these films. Characterization of the films by X-ray photoelectron spectroscopy, infrared spectroscopy, and atomic force microscopy is correlated with film growth parameters and the resulting growth kinetics. These films have broad application as hard coatings in the disk drive and optics industries, and a fundamental understanding of their growth may impact these industries as well as thin film growth in general. Multidisciplinary education of researchers in this laboratory results from these studies. A fundamental understanding of the dependence of film growth kinetics and morphology related to the composition of growth plasmas is the goal of this research being carried out in the laboratory of Professor Fairbrother at the Johns Hopkins University. Film characterization coupled with controlled growth conditions provides information about the mechanisms and kinetics of growth. This information is useful in the design of processes for the production of tribological and optical films and coatings.

在分析和表面化学计划的支持下，约翰霍普金斯大学的Fairbrother教授和他的同事们正在研究氢化非晶氮化碳薄膜生长的动力学和形态。 一个模型等离子体反应器，包括一个甲基自由基源和氢和氮离子源，用于可控地生长这些薄膜。 通过X射线光电子能谱，红外光谱和原子力显微镜表征的薄膜与薄膜生长参数和由此产生的生长动力学。 这些薄膜作为硬涂层在磁盘驱动器和光学行业中具有广泛的应用，对它们的增长的基本理解可能会影响这些行业以及一般的薄膜增长。 本实验室研究人员的多学科教育来自这些研究。 一个基本的了解薄膜生长动力学和形态的依赖关系的组成生长等离子体是本研究的目标正在进行的实验室教授费尔布拉泽在约翰霍普金斯大学。 薄膜表征加上受控的生长条件提供了有关生长机制和动力学的信息。 这些信息在摩擦学和光学薄膜和涂层的生产工艺设计中非常有用。
