Dopants in Diamond: Their Interactions and Relationships to Charge Transport in Electrochemistry

凯斯西储大学的约翰·安格斯教授和阿尔弗雷德·安德森教授将完成化学气相沉积金刚石薄膜中供体和受体掺杂剂之间相互作用的基础研究，这项工作由分析和表面化学项目支持。这个项目的目标是了解电荷通过这些表面与电解质的界面传输特性。在这个项目中，重点是用硼作为主要掺杂剂的半导体金刚石层。通过理论建模和实验技术（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）来研究表面的性质，这些技术都已成功地用于该实验室过去的工作中。金刚石薄膜在电极表面具有广泛的电位范围和低的固有电噪声等特性，可用于化学传感器和电合成领域。这个项目提供了电荷如何在这些薄膜中移动的理解，特别是那些有微量掺杂原子的薄膜。

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. .
