Molecular Interfaces in Multicomponent Films

美国国家科学基金会的分析和表面化学计划将支持马里兰大学帕克学院贾尼斯·罗特-罗比的研究计划。本项目的目标是(1)开发制备具有不同化学织构的分子薄膜的方法；(2)确定化学织构对电子性质的影响。为了实现这些目标，将通过多组分沉积制备具有不同化学织构的样品，并使用扫描隧道显微镜进行映射。相关的电子信息将通过电子隧穿和光电子发射测量获得。来自该项目的新知识将指导技术开发高效有机材料，用于太阳能转换、显示设备和电子晶体管等应用。该计划将通过提供表面分析化学方面的培训机会，并通过教育推广提高K-12学生的科学素养，为美国劳动力做出贡献。

The Analytical and Surface Chemistry Program of the National Science Foundation will support the research program of Janice Reutt-Robey at the University of Maryland, College Park. The goals of this project are to (1) Develop methods for the preparation of molecular films with varied chemical textures and (2) Determine the influence of chemical texture on electronic properties. To realize these goals, samples with varied chemical textures will be prepared via multi-component deposition and mapped with scanning tunneling microscopy. Correlated electronic information will be obtained through electron tunneling and photoemission measurements. New knowledge from this program will guide technology toward the development of efficient organic materials for such applications as solar energy conversion, display devices and electronic transistors. This program will contribute to the United States workforce by providing training opportunities in surface analytical chemistry and by increasing the scientific literacy of K-12 students through educational outreach.
