Mechanisms of laser and electron beam modifications of wide bandgap single crystal surfaces
EMSL Project ID
25106
Abstract
We propose to use EMSL capabilities to examine the nanometer scale modifications of wide bandgap single crystal surfaces exposed to UV laser and keV electron beam radiation. Previous work has shown evidence of atomic step erosion, pit formation, and the formation of single atomic layer aggregates. Our principle interest is using the EMSL UHV-AFM to perform these experiments in situ. This will allow following very small changes in surface structure so that mechanisms can be determined. This will be a team effort involving EMSL scientists Dr. Dr. Igor Lyubinetsky and Dr. Wayne Hess.
