Self-Assembled Monolayer Films: Effective Targets for Ion/Surface Collisions

该项目属于分析化学和表面化学领域，涉及对金上烷硫酸盐自组装单层（sam）的离子表面反应进行全面、系统和详细的研究。本研究的主要目标是提高我们对离子表面化学的理解，当气相多原子离子在几十电子伏特的碰撞能量下与特征良好的有机表面碰撞时，观察到离子表面化学。从这些表面诱导解离（SID）实验中获得的信息将用于改进有机表面和抛射离子的表征。Wysocki教授和她的学生将研究低能多原子离子与覆盖有自组装单层有机分子的固体表面相互作用的化学性质。该研究具有特殊的技术意义，因为自组装单层膜作为光阻剂在x射线微光刻中的潜在应用，即反应离子蚀刻。

This project, in the area of analytical and surface chemistry, involves the comprehensive, systematic, and detailed investigation of ion-surface reactions involving self-assembled monolayers, SAMs, of alkanethiolates on gold. The primary goal of the research is to improve our understanding of the ion-surface chemistry observed when gas-phase polyatomic ions collide with a well-characterized organic surface at collision energies in the tens of electron volts regime. The information obtained from these surface induced dissociation (SID) experiments will be used to improve the characterization of both organic surfaces and projectile ions. %%% Professor Wysocki and her students will investigate the chemistry of low energy, polyatomic ions interacting with solid surfaces covered with self-assembled monolayers of organic molecules. The proposed research is of special technological significance because of the potential application of self-assembled monolayers as photoresists for X-ray microlithography, i.e., reactive ion etching.
