Organic Wires and Films on Semiconductor Surfaces

Abstract

The recent demonstration of self-assembled organic monolayer films on the Si(001) surface has received widespread attention because of the possibility of combining the wide range of functionality of organic molecules with the existing Si-based infrastructures. Such a hybrid organic-silicon system can be utilized for the development of molecular electronics and various technological applications such as microscopic chemical sensors, optical devices, or biochemical monitors. In this talk I present first-principles density-functional theory calculations for various hybrid organic-silicon systems which have the structures of the one-dimensional wire and monolayer films. Our results provide the theoretical basis for the interpretation of recent various experimental data of hybrid organic-silicon systems.
