Controlled attachement of organic molecules to semiconductor surfaces is expected to enable a new class of hybrid molecular electronic devices and sensors with the potential to significantly enhance the functionality of conventional microelectronics. This research program is concerned with understanding the electronic coupling between organic molecules and semiconductor surfaces. Solution based and gas phase reactions will be employed to create high quality organic molecular monolayers on silicon substrates. The structure and electronic properties of these systems will be studied with a range of surface science probes. Electrical transport through molecule/silicon junctions and the role of molecular layers in modulating transport through the silicon substrate will both be investigated. These studies of organic molecule/silicon interfaces are expected to enable the development of novel molecular electronic devices (memory and/or logic) as well as sensors (chemical and biological).

有机分子与半导体表面的受控附着有望使一类新的混合分子电子器件和传感器具有显著增强传统微电子学功能的潜力。本研究计划关注有机分子和半导体表面之间的电子耦合。基于溶液和气相反应将用于在硅衬底上产生高质量的有机分子单层。这些系统的结构和电子性质将与一系列的表面科学探测器进行研究。通过分子/硅结的电传输和分子层在调制通过硅衬底的传输的作用都将被研究。有机分子/硅界面的这些研究有望使新型分子电子器件（存储器和/或逻辑）以及传感器（化学和生物）的发展成为可能。
