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 detailed introduction to the principles and practice of two techniques for analyzing the first few monolayers of a surface: XPS -the most common surface analytical method and ToF-SIMS a mass-spectroscopy-based method complementary in many ways to XPS. Taken together they allow:
· The detection of the elemental composition of a sample
· The detection of even trace elements down to ppm of a monolayer
· The chemical bonding between elements
· The lateral and vertical distribution of elements in the top layers of a sample
· The surface bonding and band structure of compounds including work function and band occupancy
Target Audience:
Attendance is open to the general technical community and is not limited to current Georgia Tech students or IEN users. The course will be of value to anyone needing to analyze the physical-chemical properties of surfaces including catalysts; thin-film metals and semiconductors; low-dimensional materials such as graphene, CNT's, and MoS2; polymers for food packaging or medical implants; corrosion studies in metals; among other materials. The course should prove useful to everyone from the interested novice, unfamiliar with these techniques - but with a practical need for information about the surface composition/chemistry of a sample - up to those with even a moderately advanced practical XPS or SIMS background looking to develop a deeper understanding.
