Semiconducting Diamond: Electrochemistry, Doping and Theoretical Studies

凯斯西储大学的John Angus、Alfred Anderson和Heidi Martin与他们的学生合作研究了导电钻石表面化学、电子结构和电荷传输之间的基本相互作用。在分析和表面化学计划的支持下，正在开展一项研究项目，重点是硼和硫掺杂的金刚石薄膜的生长，用电学、光学、结构和电化学方法对这些薄膜进行表征，以及吸附物的光谱表征及其对表面电导率的影响。从头计算被用来解释这项实验工作的结果。正在进行基于吸附诱导的钻石表面电导率的新型传感器的概念验证设计。详细了解吸附对金刚石电极表面导电性和电子性质的影响可用于开发新的传感器策略。目前正在进行一项实验和理论研究相结合的工作，以解决金刚石薄膜生长和表征中的这些问题。

AbstractCHE-0314688Angus/Case Western This research collaboration involving John Angus, Alfred Anderson, and Heidi Martin and their students at Case Western Reserve University investigates the fundamental interactions between the surface chemistry, electronic structure, and charge transport at conducting diamond surfaces. With the support of the Analytical and Surface Chemistry Program, a research project focusing on the growth of boron and sulfur doped diamond films, characterization of these films by electrical, optical, structural, and electrochemical methods, and spectroscopic characterization of adsorbates and their effect on surface conductivity is being undertaken. Ab-initio calculations are used to interpret the results of this experimental work. Proof of concept design of new sensors based on the surface conductivity of diamond induced by adsorption is being carried out. A detailed understanding of the effects of adsorption on the conductivity and electronic properties of diamond electrode surfaces can be used to develop new sensor strategies. A combined experimental and theoretical research effort is being carried out to address these questions in the growth and characterization of diamond thin films.
