*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

A special seminar featuring Dr. Andrew Teplyakov from the University of Delaware will take place on Monday, September 23, at 4 p.m. in Ford ES&T, room L1255.

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.
