The Analytical and Surface Chemistry (ASC) program of the Division of Chemistry will support the research program of Prof. Nathan Lewis of California Institute of Technology. Prof. Lewis and his students will investigate how to gain molecular control of processes involving the modification of silicon surfaces. Chemical modification of silicon surfaces is important in a plethora of applications including interfacing molecular electronics to Si-based circuitry, developing novel chemical sensors, developing new integrated optoelectronic devices, obtaining higher efficiencies from existing photovoltaic and photoelectrochemical cells and enabling high efficiencies of novel devices constructed from inexpensive but high surface area materials. The study will involve an extensive series of experiments designed to answer fundamental questions in silicon surface chemistry while demonstrating new chemical properties of Si surfaces. The research of Prof. Lewis will provide excellent training opportunities for students and postdoctoral research associates in a highly multidisciplinary area at the forefront of scientific research.

化学系的分析和表面化学（ASC）计划将支持加州理工学院的内森刘易斯教授的研究计划。 刘易斯教授和他的学生将研究如何获得涉及硅表面改性过程的分子控制。硅表面的化学改性在众多应用中是重要的，包括将分子电子器件与Si基电路连接，开发新型化学传感器，开发新型集成光电器件，从现有光伏和光电化学电池获得更高的效率，以及使由廉价但高表面积材料构造的新型器件具有高效率。这项研究将涉及一系列广泛的实验，旨在回答硅表面化学的基本问题，同时展示硅表面的新化学性质。刘易斯教授的研究将为学生和博士后研究助理提供良好的培训机会，在科学研究的前沿高度多学科领域。
