Self-Limiting Surface Reactions on Semiconductors: Functionalization, Film Growth, and Nanostructure Formation

Recent trends in coupling chemical functionality with desired semiconductor surfaces will be explored in this presentation. We will start with a brief historic perspective on reactivity of multifunctional organic and organometallic compounds on clean group IV semiconductor surfaces and expand this approach to include chemically functionalized and "multifunctional" surfaces and tunable chemical reactivity of surfaces. The complexity of surface structures produced even in reasonably simple chemical processes will be highlighted based predominantly on spectroscopic and microscopic surface analytical techniques. Examples of understanding local surface structures supported by DFT calculations will be given. The specific examples will also include the initial stages of thin diffusion barrier film growth and copper nanoparticle formation by self-limiting reactions.
