Professors John Angus and Alfred Anderson of Case Western Reserve University will complete fundamental studies of the interactions between donor and acceptor dopants in chemical-vapor-deposited diamond films in work supported by the Analytical and Surface Chemistry program. The goal of this project is an understanding of charge transport properties through interfaces of such surfaces with electrolytes. In this project, the emphasis is on a semiconducting diamond layer with boron as the primary dopant. Properties of the surface are studied through theoretical modeling, and through experimental techniques such as electrochemical measurements, scanning electron microscopy, atomic force microscopy, and surface tunneling microscopy, each of which have been successfully used in past work in this laboratory. Diamond films on electrode surfaces have attractive properties of wide potential range and low intrinsic electrical noise when used in devices used as chemical sensors, and used in electrosynthetic applications. This project provides the understanding of how electrical charge moves through these thin films, especially those with trace levels of dopant atoms. .

Case Western Reserve University的John Angus教授和Alfred Anderson将完成对分析和地表化学计划支持的化学蒸气剂量钻石膜中捐赠者与受体掺杂剂之间相互作用的基础研究。 该项目的目的是通过与电解质的此类表面的接口了解电荷传输属性。 在这个项目中，重点是以硼作为主要掺杂剂的半导体钻石层。 通过理论建模研究表面的性能，并通过实验技术，例如电化学测量，扫描电子显微镜，原子力显微镜和表面隧道显微镜，这些技术已成功地用于该实验室。电极表面上的钻石膜具有吸引人的特性，具有广泛的电势范围和低固有的电噪声，用于用作化学传感器的设备，并用于电合应用。 该项目提供了对电荷如何通过这些薄膜移动的理解，尤其是那些具有痕量掺杂原子的薄膜。 。
