-------------------------------------------------------------------- COLLOQUIUM OF THE LABORATORY FOR COMPUTER DESIGN OF MATERIALS School of Computational Sciences (CSI 898-Sec 001) -------------------------------------------------------------------- Density functional study of interactions of particles on surfaces Guan Ming Wang Naval Research Laboratory, Washington, DC 20375 and Center for Nanomaterials Research and Department of Chemistry, Dartmouth College, Hanover, NH Nano-size particles placed on solid surfaces have been studied with techniques such as scanning tunneling microscopy (STM). The interactions between particles, surfaces, and the scanning tip are not well understood. Yet, the 3-entity system is important to interpret the STM images correctly. I will report the density functional investigation on a few selected small particles on surfaces using an efficient ab initio tight-binding approach, which is called PLATO. Particles include adatoms, dimers, etc on solid surfaces such as graphite and carbon nanotubes. Monday , February 14, 2005 4:30 pm Room 206, Science & Tech. I, Fairfax Campus Refreshments will be served at 4:15 PM. ---------------------------------------------------------------------- Find the schedule at http://www.scs.gmu.edu/lcdm/seminar/schedule.html --------------------------------------------------------------------
