9700202 Sailor This proposal is aimed at developing the surface chemistry of silicon, and on obtaining a fundamental understanding of the radiative and nonradiative processes available to luminescent nanocrystalline silicon ("porous silicon"). Two major areas will be emphasized: the study of chemical transformations, and the study of physisorption processes at porous silicon surfaces. %%% The proposed work will advance our fundamental understanding of the relationship between surface species and carrier dynamics in porous silicon. It will aid in the design of specific chemical sensors based on modulation of the optical properties of porous silicon, which will help in the design of stable luminescent devices or chemical sensors. ***

9700202本建议旨在发展硅的表面化学，并对发光纳米晶硅(“多孔硅”)可用的辐射和非辐射过程有一个基本的了解。重点介绍两个主要领域：化学转化的研究和多孔硅表面物理吸附过程的研究。这项工作将有助于我们从根本上理解多孔硅表面物种与载流子动力学之间的关系。它将有助于基于多孔硅光学性质调制的特定化学传感器的设计，这将有助于设计稳定的发光器件或化学传感器。***
