Semiconducting Diamond: Electrochemistry, Doping and Theoretical Studies

安格斯/凯斯西储这项研究涉及凯斯西储大学的约翰安格斯、阿尔弗雷德安德森和海蒂马丁以及他们的学生，他们研究了导电金刚石表面的表面化学、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，正在进行一个研究项目，重点是硼和硫掺杂金刚石薄膜的生长，通过电学，光学，结构和电化学方法表征这些薄膜，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个实验工作的结果。 目前正在进行基于吸附引起的金刚石表面导电性的新传感器的概念设计验证。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。 一个实验和理论相结合的研究工作正在进行，以解决这些问题，在金刚石薄膜的生长和表征。

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.
