Making Metallic Contacts to Molecules

华盛顿大学的Amy Walker教授在化学系分析和表面化学项目的支持下，利用飞行时间二次离子质谱（TOF SIMS）和红外光谱（IRS）研究气相沉积金属与自组装单层（SAMs）的相互作用。量子力学计算将用于确定金属分子的键能和几何形状。将从综合实验和理论结果中构建金属-有机相互作用数据库，并制定与sam和其他薄有机表面金属接触设计和构建的一般准则。这个想法是开发简单可靠的技术，在二维和三维的有机薄膜上形成金属互连。生产稳定的金属接触到薄有机薄膜是许多战略技术的关键，包括聚合物发光二极管和分子电子学。该研究将与材料化学和纳米技术的教育项目相结合，学生将在这些重要技术领域的基础科学方面接受培训。

Professor Amy Walker of Washington University is supported by the Analytical and Surface Chemistry Program in the Division of Chemistry to investigate the interaction of vapor-deposited metals with self-assembled monolayers (SAMs) using time-of-flight secondary ion mass spectrometry (TOF SIMS) and infrared spectroscopy (IRS). Quantum mechanical calculations will be used to determine metal-molecule bond energies and geometries. A database of metal-organic interactions will be constructed from the integrated experimental and theoretical results, and general guidelines for the design and construction of metallic contacts to SAMs and other thin organic surfaces will be formulated. The idea is to develop simple and reliable techniques to form metallic interconnects to organic thin films in two- and three-dimensions. The production of stable metallic contacts to thin organic films is critical to many strategic technologies including polymer light emitting diodes and molecular electronics. The research will be integrated with an educational program in materials chemistry and nanotechnology, and the students will be trained in the basic science that underlies these important technological areas.
