Physics Seminar: Systemic Surface Science Studies of Sapphire
- 5:30 PM
Thursday Oct 3, 2013
Olin-Rice Science Center 150
Mac Visiting Professor Tom Christensen from University of Colorado, Colorado Springs.
Surface science brings together elements of physics, chemistry, and engineering to better understand properties of the top few atomic layers of materials. Experimental techniques frequently involve shooting beams of electrons and ions at surfaces which can change the surfaces even as we study them. Interesting effects resulted on sapphire surfaces of both bulk and thin film samples when exposed to electron beams as part of Auger Electron Spectroscopy and when exposed to AR ion beams as part of routine surface cleaning and then characterized with X-ray Photoelectron Spectroscopy. Further characterization allowed us to determine how to minimize the undesirable effects.
Join us at the Physics & Geology TEA at 4, then attend the talk.
