Professor Richard McCreery of Ohio State University is supported by the Analytical and Surface Chemistry Program to study the electronic properties of electrode/molecular monolayer/electrode sandwich junctions. Electrical measurements will be performed at different temperatures to determine the mechanism of charge transfer and conductance through the molecular monolayer, and in-situ spectroscopy (Raman, FTIR, UV-Vis) will be used to monitor changes in chemical bonding and in the molecular structure of the monolayer, and how these are affected while carrying out electronic functions. The project addresses fundamental research issues in a topical area of analytical and surface chemistry with high technological relevance to the field of molecular electronics. The goal is to gain understanding of the electronic behavior of a variety of molecules and rationally design molecules to perform specific electronic functions for potential applications in scientific and consumer arenas, such as high density data storage, molecular transistors, photodetectors, light emission technology, and chemical sensors.

俄亥俄州州立大学的Richard McCreery教授受到分析和表面化学计划的支持，研究电极/分子单层/电极三明治结的电子性质。 将在不同温度下进行电学测量，以确定通过分子单层的电荷转移和电导机制，并将使用原位光谱（拉曼、FTIR、UV-Vis）监测化学键合和单层分子结构的变化，以及这些变化在执行电子功能时如何受到影响。 该项目涉及分析和表面化学领域的基础研究问题，与分子电子学领域具有高度的技术相关性。 目标是了解各种分子的电子行为，并合理设计分子以执行特定的电子功能，用于科学和消费领域的潜在应用，如高密度数据存储，分子晶体管，光电探测器，发光技术和化学传感器。
